• Multiple Problems Installing 12.04, now can't use Windows

  - by user87997

  First I tried using the 32-bit wubi.exe installer from the main Ubuntu website. It worked fine, dual booted with Windows 7 and all. I tried installing several applications and got errors. After searching for a little while for a fix, I found that someone else had solved the problem by uninstalling the 32-bit version and installing 64-bit Ubuntu. Apparently there is no wubi.exe installer for the 64-bit version, so I used LinuxLive to put the iso file onto a USB drive. I changed my the boot order in BIOS to check the USB first. It did, and I got into the Ubuntu installer just fine. Everything was working fine, but then I got an error that GRUB could not be installed. I chose "install manually later" or something like that. Immediately, the installer said it was done and ready for a reboot. At this point, my USB is still in the computer. The computer reboots...and it's back at the installer for the USB. I look up what's going on here, and someone says in a thread they solved it by selecting "Try Ubuntu" then installing it via a shortcut on the desktop. I assumed that Ubuntu simply hadn't installed and it would be safe to try again, so I did. It finished installing, this time I chose a different partition that wasn't being used. The thread also said to reinstall grub to the mounted drive, so I did that. Next I took out my USB and rebooted. I get stuck on the GRUB GNU loader, v.1.99 or something I believe it says at the top. I can't do anything, and it doesn't detect Windows 7 OR Ubuntu. When I check partitions, I have two 43 GB partitions that both have the same files in them (I'm assuming those are the two Ubuntu installations), and can only run Ubuntu off of my USB-- and can't run Windows 7 at all, however from within Ubuntu the windows 7 filesystem and files can still be seen. I have no idea what to do now. I used Ubuntu in the past (9.xx) and never had these sorts of problems! Please help. And sorry for the wall of text.

• Firewire hard drive with Leopard install image won't boot from PPC Mac Mini

  - by GregH

  I have a Mac Mini (G4 - 1.25 GHz PowerPC) running osx 10.3.9. I want to upgrade it to 10.5 (Leopard). The problem is that I only have a CD and no DVD. After working through all of these issues, I got myself a firewire hard drive and both a 10.4 and 10.5 image that I could image on to the hard drive. I was able to successfully boot off the firewire drive with the 10.4 image. However, I am not able to boot off the firewire drive with the 10.5 image. When trying to boot under the 10.5 image I specify the firewire drive as the startup drive. However, it just boots to the internal (10.3) drive. Any idea why it won't boot to the 10.5 image?

• Boot ISO image from GRUB4DOS on EFI machines

  - by Vladimir Tikhomirov

  I failed with loading ISO image (non-distro) from GRUB2 from USB stick, but found the way how I can boot the GRUB4DOS and then load the image from there. However, it doesn't work all the time and the questions is WHY it doesn't? Environment and loading process: We need to have EFI machine, USB stick, booting ISO, GRUB2 and GRUB4DOS. Last 3 on USB stick. Boot: USB - EFI loader - GRUB2 - GRUB4DOS - ISO image Configuration files To boot GRUB4DOS I use this from grub.cfg: menuentry "image.iso" { linux /syslinux/grub.exe --config-file="/menu.lst" } My menu.lst is here: timeout 20 default 0 title image.iso find --set-root --ignore-floppies --ignore-cd //image.iso map --heads=0 --sectors-per-track=0 //image.iso (hd32) map --hook chainloader (hd32) This works perfectly with Legacy machines. However, when I come to GRUB4DOS, I don't see the menu with image.iso, I see only GRUB command line. That means that my menu.lst didn't load. Why is it like this? Background and ideas I have an idea that GRUB4DOS doesn't recognize my USB stick as a device. I tried the command find and got (hd0,0), (hd0,1), (hd0,2), (rd). When I tried to set root to any of these devices I don't see fat file system, how it was with Legacy machines. The root device is (hd0,0), which has ntfs file system which should be partition with Windows. EFI machines support only GRUB2, so I can't boot GRUB4DOS straight away. Please, don't suggest anything like this, because my image doesn't have kernel. You can imagine that you load HDAT2 or Hiren's boot cd, for example. menuentry "Blancco Blancco5.iso" { set isofile="/image.iso" loopback loop $isofile set root=(loop) linux /isolinux/vmlinuz isofile=$isofile splash quiet initrd /isolinux/initrd }

• Boot iMac into Centos from external hard drive

  - by user1704978

  I have Centos 6.3 installed on an external Western Digital drive with Firewire and USB interfaces. I want to be able to boot an iMac (2008, 3.06GHz Core 2 Duo) from this disk. The iMac has Mac OS X 10.5.8 and also a Window XP installation. I have tried holding 'T' on bootup for target disk mode but the external disk is ignored (presumably as it's not a Mac OSX image). I created an rEFit boot DVD which when booted in CD mode (holding 'C' on startup) displays three options, Mac OS (on internal drive), Linux and Windows. Selecting the Linux option unfortunately boots the Mac into XP. Three options are only displayed when the external disk is plugged into the Firewire port. If the external disk is plugged into a USB port the Linux option is not displayed and I can only boot into Mac OS X or Windows. This external disk will happily boot a Lenovo T410 laptop into Centos. My questions are: 1) Is it actually possible to boot into Centos on an iMac with an external hard drive. If so how do I achieve this? 2) Why is rEFit apparently booting from the wrong partition?

• OCZ Vertex 3 SSD boot failure

  - by Col Zero

  Ok, so I just purchased and received a 120GB OCZ Vertex 3. I had Windows 7 on an .ISO file on my computer. I formatted a USB stick and configured it to be read as a CD so that I could install windows onto my SSD from it. I started my comp, had the boot priority set to my USB, starting installing windows 7 to my SSD. And out of no where (I wasn't watching) my computer restarted and it brought me back to the beginning of the Windows 7 set-up. So I turned my computer off and booted it up from the SSD to see if it had installed onto the SSD. The first 2 attempts I had a disk boot failure. So I plugged my hard drive back in, started my computer, turned it off, plugged the SSD back in (literally) and it booted up fine/ Finalized windows got internet set up, and Windows had updates that required a restart. So I restarted and had another disk boot failure. Now I have a disk boot failure every time I try to start my computer up through my SSD. Extra Info: My SSD has never been able to be detected in my BIOS unless my Hard Drive was unplugged (eve then my BIOS didn't always detect it). MY SSD wasn't detected in my BIOS the first and only time it successfully booted up. My SSD literally boots up successfully randomly (only once unfortunately) and is detected in my BIOS randomly. I've tried switching cords etc and nothing has worked. I just want to get this damn thing running so I can see whats its like. I finally found a way to get the OS on this sucker and now it won't even boot up. Any help appreciated

• Two instances of Windows Vista on boot up after failed clean install

  - by Dwayne

  I tried to install a clean version of Vista but failed. I ended up with Windows and Windows.old on my C: drive and a dual boot option on boot up. I gave up and booted up the old version and tried to rename the Windows.old to Windows and was asked if I wanted to merge the two folders. I answered yes and all seemed OK until I booted up this morning and was given the choice of two versions of Vista. The first one is the one that failed to installed correctly and the second one is the old version. How can I get rid of the failed installation? I got rid of the bad boot via MSCONFIG. Here is my current situation: several hard drives installed Using C: as my boot drive a much larger drive (H:) for storing most of my files. I found a subfolder in my C:\windows folder named windows. Upon inspection I determined it to be older than the C:\windows folder and therefore it must be the older, working version of the boot. I renamed the C:\windows folder to c:\windows.bad and moved the sub windows to the C: root directory. I also copied it to the h: drive. Now MSCONFIG reports that the copy that is booting is the h: copy. How can I change it back to the C:\ copy and can I delete the C:\windows.bad file set?

  I'm want install Xen Server 6.2 though ipxe, I tried different configurations, no luck making to work until now. I found some may example to boot from pxe using TFTP server, and here is an example: default xenserver-auto label xenserver-auto kernel mboot.c32 append xenserver/xen.gz dom0_max_vcpus=1-2 dom0_mem=752M,max:752M com1=115200,8n1 console=com1,vga --- xenserver/vmlinuz xencons=hvc console=hvc0 console=tty0 answerfile=http://[pxehost]/answerfile.xml remotelog=[SYSLOG] install --- xenserver/install.img The problem is that ipxe uses different syntax, I could not figure out how to convert this configuration to work on ipxe.

• Dell XPS m1530 system cannot boot need 130w or greater

  - by KPS

  I have a Dell XPS M1530 and I lost my old AC adapter but ordered a new one. For the longest time it always had a battery charge so I was able to boot into the OS but now it is completely dead. I have a generic charger that slowly charged the laptop when it was in the OS but does not when the computer is off. When I boot up I get the following error: The AC power adapter type cannot be determined. The system can only boot with a 130 W power adapter or greater. Strike F1 key to shutdown. I cannot even enter the BIOs setup screen or boot menu, is there a way around this? I heard from the local tech that Dell has a special feature to boot from thumb drive before getting past the initial logo. I am doing my best to avoid purchasing a new charger since it worked just fine when the OS was running, I am hoping to get this thing going. Is there a way to charge the battery externally? Thanks in advance for any help!

• IBM x260m won't boot from PCI raid card

  - by syrenity

  Hi. We ghosted our old Windows 2003 drive to a new 1TB one, and connected through new PCI SATA card. The server fails to boot with error 1962: Boot sector not found. When we connect the drive directly to motherboard, it boots fine, so the problem is probably in getting BIOS boot from the SATA card. Does anyone know how to do it? Thanks.

• Boot camp with Vista crashes on startup

  - by Mark Pim

  I have a 2006 vintage MacBook Pro (Intel Core 2 Duo) and have been using Boot Camp since it was in beta. I had been running XP SP2 on it with Tiger quite happily. I've recently wiped and reinstalled everything to upgrade to Leopard. After installing Leopard, I fired up the Boot camp assistant and used it to install the Windows 7 RC. That worked really nicely, but my HFS+ driver didn't work under Windows 7 yet so I decided to install Vista instead. I didn't repartition the drive, just launched the Vista installation disk from BIOS and told it to overwrite the existing Windows 7 install. It installed fine and I installed the Boot Camp drivers, still all fine. Now, however, every time I boot into Windows and login it hard reboots itself as the desktop is appearing. After this it works fine again. Until the next power off. Has anyone had any similar problems? Or can offer suggestions on how to solve this?

• Seeking (somewhat) better explanations about supporting > 2.1 TB hard drives.

  - by irrational John

  Today while Googling about I stumbled across posts claiming that Seagate plans to ship a 3TB drive sometime later in 2010. Unfortunately, the stuff I looked at all seemed to contain tidbits of info which I didn't think fit together properly. (I would link to some examples, but I'm only allowed 1 link per post at the moment). Now I really don't have any "need" to better understand the underlying tedious details of this. I am just curious. And confused. So ... some questions I'm hoping someone better informed than I might answer. The talk about a potential addressing problem in both the hardware and the software confused me. The assertion is that something called something called Long LBA addressing (LLBA) is needed in the Command Descriptor Block as a way to get around the current limits to access a hard drive bigger than ~2.1 (or ~2.2?) TB. OK, fine. But I thought the last time this problem came up it was solved by extending the length of the LBA field from 28 to 48 bits. (Remember this website? www.48bitlba.com) A 6 byte LBA is clearly large enough, so what's up with this LLBA talk. I thought this was all fixed back by Win XP SP2, if not sooner? And certainly all the hardware should be up to the task, shouldn't it? The real problem as I understand it with drives much bigger than 2 TB are the 4 byte LBA fields in the Master Boot Record (MBR) used to partition just about all hard drives at the moment. The most likely solution is to migrate to Intel's GUID Partition Table (GPT). A GPT uses 8 byte fields for the LBA. What I don't understand in this context is what is the problem with booting say Windows from a 3TB drive that uses a GPT. Granted, the current PC BIOS wouldn't know how to recognize or work with a GPT. But every GPT comes with a so-called "Safety" or "Guarding" MBR in sector 0.Apple already uses a hybrid version of the MBR to allow them to boot Windows on their Intel Macs (aka Boot Camp). Couldn't something similar be done to allow the PC BIOS to recognize and boot from a partition in, say, the first 1 GB of a 3GB or larger drive? I've got more questions such as where do 4K sectors fit into all of this. But it's probably time I just shut up and posted this. ;-) -irrational john

  Hi. We ghosted our old Windows 2003 drive to a new 1TB one, and connected through new PCI SATA card. The x260m server fails to boot with error 1962: "Boot sector not found." When we connect the drive directly to motherboard, it boots fine, so the problem is probably in getting BIOS to boot from the SATA card. Has anyone encountered and solved such issue? EDIT: We tried disabling the on-board Sata controller (Hostraid/SAS?), but there is no such option - only enable, enhanced and compatible. Tried also to chance boot device priority to all possible choices - no luck. Thanks in advance!

• Converting software RAID1 to RAID10 for /boot

  - by luckytaxi

  Array info: /dev/md0 - /dev/sda1 and /dev/sdb1 /dev/md2 - /dev/sda2 and /dev/sdb2 Partition info: /boot - /dev/md0 / - /dev/md1 I have two drives that are setup as RAID1 using software RAID on Redhat. I added two additional drives (same size) and I would like to conver the RAID1 to a RAID10. The problem I'm having is adding the last drive to the array. I've gotten as far as creating a RAID10 with two missing devices but as soon as I add the last drive, all hell breaks loose. It seems /dev/sda1 is the culprit. What I'm not too sure about is how to create the RAID10. I've tried the following mdadm --create /dev/md2 --level=raid10 --raid-device=4 /dev/sdc1 missing /dev/sdd1 missing I then proceeded to fail /dev/sdb1 from /dev/md0 and added that partition to /dev/md2. I proceeded to install the MBR on EACH partition since boot resides on /dev/sdx1 on each drive. As a test, all is well, I'm able to boot back into the system once I do a quick reboot. Now, when I go add the last drive /dev/sda1, it breaks. I attempted to install grub on /dev/sda1 and I get the following ... grub> root (hd0,0) /dev/sda root (hd0,0) /dev/sda Filesystem type is ext2fs, partition type 0xfd grub> setup (hd0) setup (hd0) Checking if "/boot/grub/stage1" exists... no Checking if "/grub/stage1" exists... no Error 2: Bad file or directory type At this point, the array is hosed I believe. I rebooted the server and it refuses to boot.

• Arch Linux: eth0 no carrier - network fails at boot

  - by user905686

  The problem My computer is connected to a network where dhcp is required. So my network configuration in /etc/rc.conf looks like interface=eth0 address= netmask= broadcast= gateway= My deamons are DAEMONS=(!hwclock syslog-ng network netfs crond ntpd) With this configuration, Arch hangs at boot a long time at "Network" (Still it says "[done]", but after boot I have no connection). I found out two workaround: Workaround 1 remove network from deamons run mii-tool --reset eth0 and dhcpcd eth0 after boot (somehow it does not work when placing these commands in /etc/rc.local. Then dhcp work very quickly (because of the reset!). Before executing the first command, ip link show eth0 has "NO CARRIER" in output. Afterwards, it doesn´t. (Also, mii-tool first shows "no link", afterwards eth0: 10 Mbit, half duplex, link ok. Workaround 2 Change network configuration to interface=eth0 address=x.y.z.21 netmask=255.255.255.0 broadcast=xxx.y.z.255 gateway=x.y.z.254 whereas x, y, z build the specific adresses of the network (Though dhcp is used, I get a static ip). Add the commands mii-tool --reset eth0 and dhcpcd eth0 to /etc/rc.local Now network starts quickly at boot (though I don´t know if successfully), the commands in /etc/rc.local are executed and the connection is fine after login. What to do? So the problem seems to be that dhcpcd stucks at "wating for carrier" or sth. I do not like the workaround, because some deamons need network (though they seem to start). What can I do to have eth0 ready for dhcp at boot? Or is there another problem?

• Windows 7 ignores F6/F8 and will not boot

  - by P.Brian.Mackey

  I have a work PC with sophos safeguard encryption on it. Windows failed to start. When I bootup I receive an error saying a recent hardware or software change might be the cause. File: \Boot\BCD Status: 0xc0000098 Info: The windows boot configuration data file does not contain a valid OS entry. This began after the PC forced me to run a system recovery. My machine had powered down improperly (power outage?) and simply would not respond to my keyboard input to cancel the option to scan my system. After the scan "repaired" a boot file, my system crashed. Now it tells me I can insert my windows 7 disk and run recovery. I can't simply do this because of Safeguard. The system recovery can't see my encrypted drive. I tried hitting F2 to manually login to Safeguard and then selected the option to boot from media. The computer prompts me to hit any key to boot from disk...which I do, but once again it is not reading my keyboard input. I can't get F8/F6 to bypass startup files and get me to a command prompt like the old days. If I could get to a command prompt I might could recover the file windows jacked up from its backup location...though I may need to use the windows recovery disk UI to do this..??? In the past I've been able to slap in a PS/2 keyboard when the USB keyboards stop responding like this. I have no PS/2 keyboard available. Anyone have any idea how I can undo the damage windows system recovery has done with safeguard installed?

• boot failure trying to install linux distro from a cd

  - by jdamae

  Hoping someone can help me get this installation from a cd going. I'm using an older pc: hp pavillion 2.66Ghz, 512RAM with a BIOS revision of 6/30/2003. I reclaimed some an older drive (Seagate ST340810A) that seems to be working as its recognized in the bios (auto-detected) I downloaded a mini.iso of ubuntu 10.10 that I want to install and burned the image to a CD for install. My boot sequence is: First Boot Device [CDROM] and I disabled devices 2-4 so I can just force it to read first from the CDROM. This old pc also has a separate CD writer which is a Sec.Slave, so the Sec.Master is the Toshiba DVD/ROM DSM-171 drive where I placed the burned cd with the linux distro. So, with these settings I cannot get it to boot. I get the "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER". Where do I go from here? Thanks.

• AHCI, Windows 7 and can only boot with Windows DVD present

  - by Rob Pridham

  Foolishly, I installed Windows 7 with my new SSD set to IDE. I would like to change it to AHCI. I have done this before, with a different motherboard. What happens: I set the controller to AHCI in the BIOS; I also check correct boot order On boot, I get the 'BOOTMGR not found' error I use the Windows Recovery Console on the DVD Diskpart etc can see the disks, and bootrec claims to have rewritten the MBR/bootloader I reboot, same problem Recovery Console again and it detects a problem, fixes, reboots Recovery Console again and it detects the OS, and a problem - fixes, reboots I ignore the 'press any key to boot from DVD' prompt Windows boots fine I restart without the DVD and I'm back to square one That optional 'press a key to boot from DVD' stage is something that the recovery process introduces - normally you have to choose to boot to the DVD at the BIOS stage. You also see this when installing Windows. I suspect that whatever temporary state that is is compatible with AHCI - but not the standard it returns to. I have done the msahci/iaStorV registry hacks to no avail (this worked with the previous board). I can put it back to IDE where normal service is resumed. The board is an Asus M5A99X, the southbridge is AMD SB950, and this is Windows 7 x64. I would quite like not to have to reinstall it again. Any ideas as to what I can do as a permanent fix?

• Can't boot from CD

  - by Jason Swett

  I installed Ubuntu on a PowerBook G4 and it only works about 10% of the time. For this reason I decided to re-install OS X, but my machine won't boot from CD. It also won't boot Ubuntu the vast majority of the time, so I'm kind of screwed. After a ton of tries, I finally got my machine to boot a Linux command line. Is there anything I can do at this point to make my machine more runnable, just for the sake of installing OS X?
