  • Generating new SID for Windows 7 cloned partition in Linux?

    - by Jack
    So I've read that the proper way to clone a Windows 7 partition is to run a Sysprep after the clone is complete. For MANY reasons, this is not possible the way we are cloning these drives (long story short, the drive should be fully up and running after we clone it, with all the settings already there and requiring no user intervention; and no, not even an answer file would work because the way we customize all the Win7 settings is complex and we do not want the user touching the settings). I understand Microsoft will not support Windows 7 clones if it is not sysprepped and that is fine for us. Acronis recovery tools get around this by ticking an option called "Create new NT signature", which resets the SID and GUID on any restore. Symantec has a tool called Ghostwalker which does the same thing. However, we are looking for a way to do this in Linux because we want to use open source tools to do the imaging (fsarchiver, partclone, etc. basically the same tools Clonezilla uses internally to clone NTFS partitions). The question is, if we clone using these tools in Linux, how would we generate a new SID thereafter (without the use of sysprep)? Is there any way to do it within a Linux environment? The whole image process is automated so if it is a simple command that I can just throw in my shell script, that would be even better. Of course, it would be nice to know if this is even possible. Any ideas? EDIT: Forgot to mention that the target machines we are restoring the image on are EXACTLY the same.

  • Which upgrade path for disk IO bound postgres server?

    - by user41679
    Hi all, We currently have a Sun x4270 with 2xquad core Xeon Nehalmen 2.93ghz cores (16 threads), 72 gig of ram and 16 x 10k SAS disks split between the os raid 1, a partition for the Write Ahead Logs which is raid 10 and a partition for the database tables and indexes which is also raid 10, all xfs. I'm currently evaluating which path to go down in terms of upgrades. We'll be sharding the DB at some point soon, but for now I need to focus on hardware upgrades specifically. The machine is not CPU or memory bound at all at the moment, just IOWait is become an issue. The machine is mostly write access as we have a heavy caching layer. We're seeing about 300 write IOPS average on both the database partitions. We don't have any additional storage infrastructure like a Fiber Channel or ISCSI network. Budget isn't too much of a concern, something inline with the size of this server (i.e no $1m IBM machines) Space is ok on the DB side of things, we're running out obviously but there's also some reduction we can do. Additional space would be good though. My current thoughts are either: * ISCSI SAN, possible with 10Gbit network that has solid state acceleration. * FusionIO card / Sun F20 card (will the FusionIO card work in the Sun box? * DAS shelf (something like this http://www.broadberry.co.uk/das-direct-attached-storage-servers/cyberstore-224s-das) which a combination of 15k sas disks and some Intel X25-E drives for DB indexes etc) what would I need to put in the x4270 to add a DAS shelf? I think it's a SAS HBA card, do I have to use Sun's own card or will any PCI Express card work? Anything else??? what would you guys do from your experience? I appreciate it's a lot of questions, but I haven't expanded a DB machine for a number of years and the landscape has changed dramatically since then! Any advice or feedback would be very much appreciated. Let me know if there's anything else I can clarify. Thanks in advance!

  • Repairing hard disk when Windows installation disk won't boot

    - by Echows
    I'm trying to recover some data from a faulty hard disk with Windows installed on it (on which Windows won't even boot). I have tried so far: Booting to Ubuntu live USB stick and running ntfsfix (didn't work) Trying to mount the broken partition when running Ubuntu from usb stick (doesn't mount) Running photorec image recovery tool from live Ubuntu (it found some stuff but not the images I was looking for) Now as a last resort I got myself a Windows installation on a USB stick so that I can try fdisk, but the installer doesn't work. The loading screen shows up and then the installer crashes. The installer works fine on other computers. I suspect that the installer is trying to read the hard drive to see if there's something there but when it can't read one partition, it crashes. On Ubuntu, I can mount other partitions except the one I'm interested in so at least the hard drive is not completely dead. So the question is, what options do I have left? To be more specific, my goal is to recover some images from the faulty ntfs-partition on the hard drive. Other than that, I don't care about the contents of the hard disk.

  • New SSD, is the MBR broken? DISK BOOT FAILURE

    - by Shevek
    I've been running Windows 7 on a WD 500gb SATA single drive, single partition setup for some time with no issues. I've just installed a new Kingston V Series 64gb SSD and performed a clean install of Win7 to it, deleting the partitions on the 500gb and using that as a data drive. All was well for a few reboots but then I started to get "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" messages. If I put the Win7 install DVD back in the drive it boots fine. Tried a clean install again, after replacing SATA cables and swapping SATA ports, with a complete partition wipe of both drives. Again, rebooted fine a few times then back with the "DISK BOOT FAILURE" error. Looked on the web and found some discussions about it so I then started from scratch again. This time I wiped the MBR on both drives using MBRWork, disconnected the 500gb and reinstalled to the SSD. Removed the install DVD and installed all the drivers which involved many reboots, all with no problem. To make sure I also did a few cold boots as well. Reconnected the 500gb, initialised, partitioned and formatted it. Copied data to it and did some more reboots and shutdowns. All was ok. Then out of the blue comes another "DISK BOOT FAILURE" and again, if the Win7 install DVD is in the drive it boots fine. So, is the SSD a bad'un? TIA UPDATE: It was a BIOS issue! I found a hidden away option for HDD boot order, which was separate from the usual HDD/CDRom/FDD boot order option. The WD was set to boot before the SSD... Swapped them round and all is well. Still don't understand how it worked at first though... Thanks Solaris

  • Share Firefox/Thnderbird data between W7 and Linux Mint 12 in dual boot computer

    - by Albert
    I've just set up my laptop (where I had running only W7) with a dual boot to run Linux Mint 12 as well. I have a "Data" partition (apart from the required partitions for W7 and Linux) where I store pretty much everything that isn't software installations (music, videos, project files, etc). I seem to be able to access that NTFS partition totally fine from Mint (like I've always done with W7), which is cool because I can access all that stuff regardless of which OS I'm using. I would like to know if it's possible (and how) to go one step further and share programs data between the two OS. One example would be my Firefox and Thunderbird data. For example, in Firefox share my bookmarks (and if I could share history, autocomplete and all that stuff, that would be awesome). In thunderbird, be able to share my mail and configuration, seeing the same inbox, folders, message rules, etc... So if I receive/send an email from W7 and later switch to Mint, I can see that email as it had been received/sent from Mint, and vice versa. Is this even possible? Or am I asking for too much convenience? If it's possible, any clues on how to set it all up?

  • linux: mount old ATA disk to USB adapter

    - by 130490868091234
    I am trying to recover data from an old Linux that was installed in a computer on an ATA hard drive. I found a ScanLogic Corp. SL11R-IDE IDE Bridge (04ce:0002), an ATA adapter to USB 1.0 like the one in the picture: and after switching it on, I plugged it into a laptop with Ubuntu 12.04. I am used to the drives being automatically mounted, but this one doesn't show up in /media. After doing a dmesg, all I got is this: [215298.671924] usb 2-1.1: new full-speed USB device number 5 using ehci_hcd [215298.767330] scsi19 : usb-storage 2-1.1:1.0 [215299.841701] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.017258] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.197050] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd [215300.372730] usb 2-1.1: reset full-speed USB device number 5 using ehci_hcd I tried plugging in the adapter to the three different USB ports in my laptop (one of them USB 3.0), but got no luck with any of them. I get different devices under, for example: /dev/bus/usb/003/002 or /dev/bus/usb/002/004, but I don't get any /dev/sdbN links. The output blkid -o list -c /dev/null is just the laptop's partitions. I have tried taking out the jumper, putting it as master and as CS Enabled, but didn't change the result. Any ideas?

  • How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

    - by sauparna
    I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

  • What is the quickest and safest way to test new software and revert all changes, if needed?

    - by calbar
    I'm looking for Windows software that will allow me to quickly create a "checkpoint", do whatever I might need to do to my computer - install programs/drivers/updates, create/delete personal files, reboot the system multiple times, open questionable attachments - and then revert the entire system back to when the checkpoint was created. Essentially I want Windows Restore Points that save my personal files and partitions, too. It sounds like disk imaging might be the ticket, but creating them is much too slow and the restore process too involved... I'm hoping to sacrifice full disaster recovery for speed. Creating a checkpoint should be as close to one-click as possible, and rolling back should be a matter of selecting a restore point and rebooting. Ding! I'm familiar with Sandboxie, True Image Home "Try and Decide", Returnil, and a number of other "virtual system" apps that actively "catch" changes and allow you to commit or reject them. I'm not interested in these for a number of reasons - I prefer the "cut and dry" restore point approach. Finally, I'll note that I've just recently become aware of Comodo Time Machine. It sounds absolutely perfect, however, a quick skim through the user forums show more than a few horror stories of corrupted, unbootable systems. Any positive personal experience with the software to suppress my superstitions, or suggestions for more established alternatives would be greatly appreciated - Comodo Time Machine seems relatively new. Thanks for your help!

  • effective back-up using Raid / Win7 back-up

    - by Job
    I have a stand-alone pc system with two 2 tb harddiscs, one of which configured as Raid1, i.e. mirorring. The operational drive is partitioned. I use an external 1 tb harddisc for back-up using Windows 7 back-up facility which will be swapped weekly and stored on other premises. I back-up all partitions AND allow a system back-up. All application software is on the C: partition. Questions: How can I see whether Raid1 is working; i.e. is doing its job. All I see now is a status message in the start-up procedure that says its status is normal. How can I see used or available space on Raid 1? The Win-7 backup allows for 1 schedule only as far as I can see. I want daily back-ups of data. However due to the single schedule I am forced to do the time-consuming system back-up and c: back-up as well. Is there a way to activate two schedules allowing a frequent (daily) data back-up and a system back-up with c: drive back-up on a say weekly basis? Of course it can be forced by hand but I am likely to forget that. I am not the programming type of person so looking for simple and controllable solutions. Thank you - any help is apreciated.

  • Move OS from RAID5 array to RAID 1 arrays

    - by Antoine
    I want to give a last boost to my old ProLiant ML350 G5 server which just needs to be reliable for a few more year only ! With a defined budget of about 1500$ (I do not have more), i plan to replace the CPU (+ adding a second one), the battery cache of my raid controller (E200i), double the RAM, and change all hard drives. I have 7 HDD (SAS 10krpm, 72Gb) + 1 spare in RAID5, and my system is all FULL (no empty tray, full disks). in my current RAID5 array, I have 2 partitions: - 1 OS partition, 20Gb - 1 data partition, 350 Gb I plan to replace these 8 disks with : - 2 x 300Gb SAS 15krpm in RAID 1 (= 1 partition for OS) - 2 x 2Tb SATA 7.2krpm in RAID 1 (= 1 partition for DATA) My biggest constraint is that I have only 01 day to upgrade my server. Therefore, I'm looking for cloning all my files (OS + data partition) to my new arrays, i.e : - the OS partition shall be cloned to the RAID1 "2x300Gb array" - the data partition shall be cloned to the RAID1 "2x2Tb array" My second problem is that I need to physically remove all the old hard drives before inserting the new ones. I'm running Windows Server 2003 R2, and even if MS support will expire soon, I cannot buy a new licence and spent time in configuration. Obviously, with 1500$, I cannot also buy a new server that I could start configuring from now ! Thought about ASR (NTBackup), but I have no floppy drive (and do not really want to invest in one !) Thought about a clonezilla clone, and read this interesting link : Windows Server 2003 - move C: partition to a new SAS disk , but i'm not so confident in using Clonezilla with RAID5. What should be the best option to quickly and easily (if possible!) "copy/paste" my OS (so no need to reinstall and reconfigure all) and DATA / programs / services, etc... ? Thanks for your comments

  • Unable to mount root fs over NFS [on hold]

  • What are the replacement options for an IDE hard disk for a DOS based system?

    - by dummzeuch
    I have got a few "embedded" systems running MSDOS 6.2 which boot from and store data to IDE hard disks. Since these drives are nearing their end of life, the question arises how we can replace them. The requirements are: DOS must be able to install and boot from these drives. They must be able to sustain heavy (mostly) write access. If possible, they should be able to survive moderate vibrations (not too bad since the current hard disks have survived several years of that) I considered the following options so far: other ide hard drives: Unfortunately modern IDE drives are too large so DOS cannot boot from them even if I create small partitions. Older IDE drives are just that: old, so they are probably not the most reliable ones any more. SSDs: There are a few SSDs with IDE interface available. I have not yet tried them. Does anybody have any experience with them? They look like the ideal replacement provided that DOS can boot from them and that writing speed does not deteriorate too much (the old hard disks are no race cars either). Compact Flash: There are adapters for using CF with IDE controllers and they work fine. DOS can boot from them and they have no problems at all with vibrations. What I am not sure about is their durability. DOS uses FAT so some very few sectors are written every time the medium is being written to. IDE to SATA converters: I have no idea whether they are any good. Has anybody tried them? It might be an option to use one of these to connect an SATA SSD to the system. Are there any alternatives that I have missed? (We are working on replacing these systems, but it will still take a few years.)

  • Removing extended partition without deleting logical in it

    - by HisDudeness
    I'm running a Linux-based laptop, and in order to multi-boot several distros in it, I created an extended partition which contains a bunch of logical ones with GParted. Now, after quite a long time with this setup, I've changed my mind because of the consequent lack of storing space for my data partition. Now I want to keep one distro alone like it's normal, and eventually have some other operating systems stored in external supports to plug in and use if I want. Obviously, also this partition I want to keep (and to enlarge a little too) is just a logical inside the extended I want to keep. For what concerns the number I'm ok, meaning I currently have this big distro dedicated extended, the swap and the data partitions, so there's space for another primary before I delete the extended, but I don't know how to delete it without touching the logical in it, I don't want to reinstall the system losing all changes and settings, and I don't want to keep an extended partition for a logical alone. How can I do? Do I have to create a new primary, copy the logical content in it and then delete everything? Will the system boot and maintain exactly all the features it has now? Or is there a way to convert an extended into a primary once it contains just one logical? Or can I directly move a logical out of an extended turning it into a primary? Or, again, am I screwed?

  • Need a place to store a few bytes of meta information on storage media

    - by Jason C
    I'm working on an embedded project. I need a place to store some filesystem-independent meta information on a storage device. The device has an MSDOS partition table. The device also may have unallocated space (depending on its size) but it will be TRIMmed (and also may be blown away by new partitions in the future). I need a location on the device that is not unallocated and that has a low risk of being touched (outside of completely erasing the device). The device is only guaranteed to have an MBR at the point the meta data needs to first be written; meaning there are no EBRs/VBRs present that I could use. There are 446 bytes at the very start of the device available for MBR bootstrap code. Currently my only idea is to store data at the end of this block. However, the device is bootable and I have no way of knowing if I'd be blowing away bootstrap code or not. The sector size is 512 bytes and the MBR is the first sector, I'm pretty sure (correct me if I'm wrong) that that means the second sector is available for use by partition data, so I can't use that either. Does anybody have any ideas? I need 4 bytes of space.

  • why does the partition start on sector 2048 instead of 63

    - by gcb
    I had two drives partitioned the same and running 2 raid partitions on each. One died and I replaced it under warranty for the same model.

  • VMWare ESXi 5 - Expanded RAID 5 array - cannot access datastore

    - by Dayton Brown
    I'm using VMWare ESXi 5 and had a 2 TB RAID 5 setup on an HP DL360 with a P400i RAID card. I added two more 1 TB drives and using the SmartStart ACU, added the drives and expanded the logical disk. Now after booting back to ESXi, the server boots, but lists no available persistent storage. I've rescanned multiple times to no avail: the Datastore doesn't show up. I booted to GParted and the 1.8TB partition shows up, but it shows as unknown. Anyone have any good ideas? EDIT: Final Solution So after much gnashing of teeth, it was fairly simple to solve. I purchased an eSata 2 TB external drive and a PCI eSata card for my server. I then used Clonezilla to image the current partitions to my new external drive. You have to check "don't check drive sizes" in advanced mode, otherwise it will yell at you for have a smaller drive. For some reason my PCI card wouldn't boot on my HP server, so I hooked the drive up to another desktop I had, booted to VMWare, and copied the vmdk's to another drive. I'm going to blow out the RAID config and then create 1.5TB logical drives.

  • Recover hard disk from Raw format

    - by user1632736
    I have been all over the web today with no results. So my drive was encrypted (truecrypt) the whole drive where windows resided. I decided to partition it to install W8 and forgot it was encrypted. So the drive got damaged and not accessible. When connected to a computer it asks for formatting. Somehow I enabled the drive through TrueCrypt on another computer and I could see and get all the files. Then I decided to decrypt the drive thinking that everything would be back to normal. After decryption my drive is not NTFS it is in RAW format. I am trying every possible way to recover, and I am desperate enough to ask lol. I tried: ddrescue (linux) (not mountable, no signature, ntfsfix no good) testdisk (linux and windows) Sees the partitions but cant do anything Many recovery applications. etc etc. I read in different places that doing a quickformat to NTFS and then doing a data recovery might help. I would definitely like a second opinion. Any suggestion would be really helpful

  • Replace Linux Boot-Drive | ext3 to btrfs

    I've got a headless server running Debian Linux currently. Linux vault 3.2.0-3-686-pae #1 SMP Mon Jul 23 03:50:34 UTC 2012 i686 GNU/Linux The root filesystem is located on an ext3 partition on the main harddrive. My data is located on multiple harddrives that are bundled to a storage pool running with btrfs. UUID=072a7fce-bfea-46fa-923f-4fb0827ae428 / ext3 errors=remount-ro 0 1 UUID=b50965f1-a2e1-443f-876f-578b5f93cbf1 none swap sw 0 0 UUID=881e3ad9-31c4-4296-ae60-eae6c98ea45f none swap sw 0 0 UUID=30d8ae34-e2f0-44b4-bbcc-22d761a128f6 /data btrfs defaults,compress,autodefrag 0 0 What I'd like to do is to place / into the btrfs pool too. The ideal solution would provide the flexibility to boot from any disk in the system alike, so if the main drive fails I'd just need to swap another one into the main slot and it would be bootable like the main one. My main problem is, everything I do needs to result in a bootable system that is open to ssh logins via network as this server is 100% headless so there is no possibility to boot it from a live cd or anything like that. So I'd like to be extra sure everything works out fine :) How would I best go about this? Can anybody hint me to guides or whip something up for these tasks? Anything I forgot to think about? Copy root-data into btrfs pool, adjust mountpoints,... Adjust GRUB to boot from btrfs pool UUID or the local device where GRUB is installed Sync GRUB to all harddrives so every drive is equally bootable (is this even possible without destroying the btrfs partitions on the drives or would I need to disconnect the drives, install grub on them and then connect them back with a slightly smaller partition?)

  • Grub error 18, gparted not showing anything

    - by Montecristo
    Some week ago I started having some problems with my pc, sometimes it just freezed not allowing me to do anything. I had to turn it off and on and sometimes do it a couple of time even at startup. Now it does not start at all, grub is giving me error 18. I have found that a solution is to create a bootable partition in the first sector of the disk. gparted does not recognize any partition, the window in which there would be my partitions is empty. sudo fdisk -l does not output anything. If I type sudo mount /dev/sda and then tab tab to autocomplete these are the devices coming out: sda sda1 sda2 sda5. If I launch sudo mount -t ext3 /dev/sda1 disk I get the following error: mount: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so dmesg outputs [ 1831.974847] EXT3-fs: unable to read superblock Do you know how to solve this issue? I'm not completely sure this is a software problem, should I try with a new hard disk?

  • Can I boot up a virtual machine natively?

    - by Anshul
    My question is: Is is possible to run a virtual machine natively on your hardware if you have installed the proper drivers etc? In other words, can I use a VHD as a regular hard drive to boot from? The reason I want to do this is that I do both graphics-intensive and audio-intensive work, but my computer is not powerful enough to handle both at the same time and many times I install a bunch of audio programs that I don't want affecting the stability of my graphics programs. Basically I wanted to have sandboxing between the two sets of applications. So I tried running the graphics-intensive programs in a VirtualBox VM and the audio-intensive work natively (simply because it's a pain to route ASIO audio devices in/out of VirtualBox). This kind-of works - the graphics-intensive stuff is tolerable, but still relatively slow, because it's running inside a VM. So my next idea was to just dual-boot and install the graphics and audio programs in separate partitions but I frequently use them in tandem, so it wouldn't be practical to reboot my machine every time I need to use the other set of programs. But I could live with this scenario: If I need to do more audio-intensive stuff, I'll just boot up to the audio partition and run the graphics programs in a VM, and then when I'm working heavily on the graphics part, I'll just boot the graphics partition as a regular OS directly on the hardware. Is this possible? For example by booting up a VHD as a regular hard drive? Or by setting up dual-boot, and every time the audio partition is shut down, synchronize the graphics VM VHD with the native graphics partition? Is it practical, given the above scenario? And if it's not possible, barring buying another computer, can anyone suggest a best-of-all-worlds setup (the two worlds being performance, sandboxing, and running in parallel) for the above scenario? Thanks in advance.

  • How to migrate WinXP from failing old HD to new one

    - by Péter Török
    Following this issue, we have all our important data backed up now. I also bought and installed a new replacement hard disk (WD 160GB PATA) as secondary (slave) drive. I created two primary NTFS partitions on it: a 40 GB system partition, and a 110GB data partition. In theory I could start reinstalling WinXP from scratch on the new system partition, then copying over all user data from the old drive to the new data partition. Once this is done, I could even throw away the old drive, or keep it just to see what happens. (Note: I don't want to clone the whole drive as it contains a dual boot setup with an old Linux installation which I don't need anymore, and anyway, a fresh reinstall would do WinXP good to get rid of many years' clutter.) However, I am lazy :-) The old HD is still functioning, the problem has not manifested again since. So I feel there is no need to hurry with a complete OS reinstall. What I don't know though is whether I will be able to install WinXP on the new system partition at a later stage without affecting the contents of the data partition on the same drive. If this is possible, I can just move over all our data to the new data partition to have it safe, then continue running WinXP from the old drive as long as it works. Does anyone see any problems/risks with this plan?

  • how can i move ext3 partition to the beginning of drive without losing data?

    - by Felipe Alvarez
    I have a 500GB external drive. It had two partitions, each around 250GB. I removed the first partition. I'd like to move the 2nd to the left, so it consumes 100% of the drive.

  • Ubuntu via Wubi refuses to show up in boot menu

    - by Redandwhite
    I'm in this strange situation: I have 3 partitions, one for Vista (C), one for Windows 7 (D), and one 10GB partition (E). At least that's how my original OEM Vista partition sees them. The primary OS that I boot into everyday is Windows 7. The situation is that for some reason it sees the Windows 7 partition (its own) as drive C, the 10GB one as (D) and the Vista one as (E). I've successfully used the Wubi installation before on Vista, but now it simply doesn't work. Ubuntu just does not show up in the boot menu, no matter what I try to do. I'm running out of ideas. I heard it doesn't really play well with Windows 7 either. I set it to Vista compatibility mode and that didn't work, I also tried installing it from Vista itself and that didn't work either for some reason. Any ideas what I should try? If anyone is about to suggest EasyBCD, please underline the command-line instructions I'm gonna need to follow. Thanks.

I am able to boot into Linux and Mac OS fine, but not into Windows anymore. The Windows system is located on /dev/sda1. I can not recall how exactly have I used testdisk but it once said that ¨The harddisk /dev/sda (160GB / 149 GB) seems too small! (< 172GB / 157GB)¨ or something simillar. So far I have tried to ¨fixboot¨ and ¨chkdsk¨ from a recovery console on the affected windows partition (/dev/sda1), the plug off power cord for 15 seconds trick, reinstalling GRUB, repairing the MFT and boot sector of the affected partition via testdisk, what next please ? Thank you!
