  • How many bootable partitions are possible to have on one hard drive?

    - by draiden
    This may not be the correct place to post this; if that's the case, just let me know and point me in the right direction please! I'm thinking of building a box that needs to be lightweight and portable, and would need to be able to boot multiple installations of windows. I am needing to have multiple installations so that I can, for example, plug the box in to the network at one location, boot in to that location's partition, and have full access to everything I would normally need to do on a computer that has already been set up on that network. Then, when I go to the next client, I would be able to do the same thing, with the new location's partition, and have all of those network settings, drive mappings, etc., available there. Obviously I'd need to go through and set them all up on the different locations/networks, I'm not expecting it to magically know where I am and what I'm doing. It would be like I'm carrying around a computer that is configured for each place I need to go in one little box, instead of having to have multiple computers or having to reconfigure all the settings and such every time I go to another client. Or is there an easier way to do this that I haven't learned of?

    i have question about hoare partition method here is code and also pseudo code please if something is wrong correct pseudo code HOARE-PARTITION ( A, p, r) 1 x ? A[ p] 2 i ? p-1 3 j ? r +1 4 while TRUE 5 do repeat j ? j - 1 6 until A[ j ] = x 7 do repeat i ? i + 1 8 until A[i] = x 9 if i < j 10 then exchange A[i] ? A[ j ] 11 else return j and my code public class Hoare { public static int partition(int a[],int p,int r) { int x=a[p]; int i=p-1; int j=r+1; while (true) { do { j=j-1; } while(a[j]>=x); do { i=i+1; } while(a[i]<=x); if (i<j) { int t=a[i]; a[i]=a[j]; a[j]=t; } else { return j; } } } public static void main(String[]args){ int a[]=new int[]{13,19,9,5,12,8,7,4,11,2,6,21}; partition(a,0,a.length-1); } } and mistake is this error: Class names, 'Hoare', are only accepted if annotation processing is explicitly requested 1 error any ideas

  • Sony VAIO with Insyde H2O EFI bios will not boot into GRUB EFI

    - by Rohan Dhruva
    I bought a new Sony Vaio S series laptop. It uses Insyde H2O BIOS EFI, and trying to install Linux on it is driving me crazy. root@kubuntu:~# parted /dev/sda print Model: ATA Hitachi HTS72756 (scsi) Disk /dev/sda: 640GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 274MB 273MB fat32 EFI system partition hidden 2 274MB 20.8GB 20.6GB ntfs Basic data partition hidden, diag 3 20.8GB 21.1GB 273MB fat32 EFI system partition boot 4 21.1GB 21.3GB 134MB Microsoft reserved partition msftres 5 21.3GB 342GB 320GB ntfs Basic data partition 6 342GB 358GB 16.1GB ext4 Basic data partition 7 358GB 374GB 16.1GB ntfs Basic data partition 8 374GB 640GB 266GB ntfs Basic data partition What is surprising is that there are 2 EFI system partitions on the disk. The sda2 partition is a 20gb recovery partition which loads windows with a basic recovery interface. This is accessible by pressing the "ASSIST" button as opposed to the normal power button. I presume that the sda1 EFI System Partition (ESP) loads into this recovery. The sda3 ESP has more fleshed out entries for Microsoft Windows, which actually goes into Windows 7 (as confirmed by bcdedit.exe on Windows). Ubuntu is installed on sda6, and while installation I chose sda3 as my boot partition. The installer correctly created a sda3/EFI/ubuntu/grubx64.efi application. The real problem: for the life of me, I can't set it to be the default! I tried creating a sda3/startup.nsh which called grubx64.efi, but it didn't help -- on rebooting, the system still boots into windows. I tried using efibootmgr, and that shows as it it worked: root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager root@kubuntu:~# efibootmgr --create --gpt --disk /dev/sda --part 3 --write-signature --label "GRUB2" --loader "\\EFI\\ubuntu\\grubx64.efi" BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 root@kubuntu:~# efibootmgr BootCurrent: 0000 BootOrder: 0002,0000,0001 Boot0000* EFI USB Device Boot0001* Windows Boot Manager Boot0002* GRUB2 However, on rebooting, as you guessed, the machine rebooted directly back into Windows. The only things I can think of are: The sda1 partition is somehow being used Overwrite /EFI/Boot/bootx64.efi and /EFI/Microsoft/Boot/bootmgfw.efi with grubx64.efi [but this seems really radical]. Can anyone please help me out? Thanks -- any help is greatly appreciated, as this issue is driving me crazy!

  • Restoring Mac-bootcamp-windows-partition image to Windows machine

    - by jpwagner
    Hi, I'm running Windows XP sp3 on my mac using bootcamp. Objective: I'd like to move this partition to a windows machine. This is what I tried: 1. create image using winclone 2. restore drive to disk partition on windows machine using paragon 3. reboot from new partition Results: it attempts to boot in XP (windows flag and progress bar load screen) but then gives me the old BSOD. safe mode just hangs while loading. (I then uninstalled KB977165 on a hunch, but that did nothing to help the issue.) Any ideas, advice, etc would be greatly appreciated. Thanks!

  • Resize partition of Windows 7 running on VirtualBox with dynamically allocated storage

    - by Nicolas Raoul
    I run Windows 7 inside VirtualBox. I resized the disk of Windows 7 from 25 GB to 50 GB: VBoxManage modifyhd Windows\ 7\ Pro.vdi --resize 50000 0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100% PROBLEM: I can' grow the partition, neither with Windows 7 itself nor with GParted: It looks like VirtualBox does not tell the client OS about the new size. What additional step is necessary?

  • Why create many partitions?

    - by ryeguy
    I have noticed that when installing Ubuntu some people create multiple partitions for directories. Like one for root, one for home, one for boot. What is the advantage to doing this over installing them all on one partition, assuming there is only one hard drive?

  • 2nd Bootable partition P2V conversion

    - by Vendoran
    I have a dual boot machine (Win7 RC and Win2008) and want to migrate one of the partitions (Win2008) into a Virtual Hard Drive and the be able to use it in VPC or Virtual Server (not Hyper-V). The ways I've seen via Linked Virtual Disks or WinImage take the entire physical drive instead of just the partition. Any ideas? Thanks in Advance, --Aaron

  • [Ubuntu]df Total size is not correct compared with the size of the disk

    - by John John
    I'm running Ubuntu Squeeze and on one of the partitions df is showing the Total size as 335G: Filesystem Size Used Avail Use% Mounted on /dev/sdb 335G 225G 94G 71% /mnt However in the past it was showing as 360GB (which is the actual size): fdisk -l /dev/sdb Disk /dev/sdb: 365.0 GB, 365041287168 bytes lsof +L1 does not return anything (and anyway if this would be the case the Total space should not be affected.) On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.

    - by GregC
    I am trying to create a software stripe setup with two physical disks (underneath they are 128K stripe, RAID5 for each). I've read that one can use diskpart, but I am unable to come up with a command that works. This is on Server 2k3 SP2. I was trying create volume stripe disk=2,3 align=1024 Diskpart errors out: The arguments you specified for this command are not valid. P.S. Tried successfully with a basic disk and a primary partition. Please reply, -Greg

If i remove internal hd and boot it will get stuck at login screen. Is there any way i can force drive letter c: to my boot partition on external hd while booting from it.

  • Best way to partition 1TB (Linux&Windows7)

    - by Simon
    Any intelligent way to partition 1TB and be prepared for resizing/adding/deleting partitions? I was thinking about LVM, but as far as i remember, Windows7 can't be installed on logical volume right? For now my plan is: - ~150GB for Windows7 and other stuff (VisualStudio..., maybe I'll split it 100/50 or something like that) - simple NTFS - 850GB = LVM - disk for linux (Ubuntu) and other stuff virtual machines etc. I'm mostly interested in how and what tools should I use to get easy in maintain partitions for both systems.

  • Splitting a MySQL DB in two may ease server from "Too many connetions"? I don't think so

    - by Petruza
    I was requested to split a MySQL in two, it's kind of a horizontal partition, in which some rows correspond to one site, and some other correspond to another site. But they want to split it in two DBs in the same MySQL server. I'm no DB expert but I guess keeping them in the same MySQL server with the same amount of memory and processor and the same platform won't improve things. What we're trying to avoid is the "Too many connections" problem.
