Ubuntu Installation :: Grub2 Cannot Boot Windows 7 (error 0xc0000225)
Jul 2, 2011
I have Lucid installed on a computer. I added a second drive, installed Windows 7. Windows 7 boots fine if it is the only drive connected, or it is selected as the boot drive in the BIOS. I booted into Lucid, ran 'sudo update-grub' and it found the Windows 7 install on the second disk. When I try to use that Grub entry to boot Windows 7, I get this error screen:
Code:
Windows Boot Manager Windows failed to start. A recent hardware or software change might be the cause. To fix the problem:
1. Insert your Windows installation disk and restart your computer.
2. Choose your language settings, and then click "Next."
3. Click "Repair your computer."
If you do not have this disk, contact your system administrator or computer manufacturer for assistance.
File: BootBCD
Status: 0xc0000225
Info: An error occurred while attempting to read the boot configuration data.
I seem to remember in the Grub 1.x days there was a map command that would 'swap' the drives so Windows would think it was the boot drive, but the Grub2 autogenerated command doesn't have anything like that.how to get Grub2 to boot Windows 7?

i initilally installed ubuntu 9.10 then installed windows 7 ,then i recovered grub2 using livecd as told in the post [URL] i did "sudo update-grub" and got windows 7 menu entry but when i select that entry windows 7 does not load but the grub2 is reloaded again.
i cant boot to windows 7.
Windows 7 have 100 mb partition "System Reserved" the grub2 points to that partition but still windows 7 not loaded.

I went through so many post but I haven't found the proper answer yet hope you have an Idea1. Grub2 saves only Linux OS as last selected no Windows OS2.It is possible to boot into a cdrom (drive)?

I have a Windows Vista-Ubuntu 11.04 dual-boot. However, I have lost the ability to boot Windows Vista. I can select Windows in the GRUB menu, but GRUB says
Quote:
error: symbol not found: 'grub_err_printed_errors'
I have repeatedly searched Google for any help, but have found nothing that applies to my situation. I need Windows because I have an iPod Touch with a tethered jailbreak and can't use it right now.

I have a asus eeepc 1101ha. With Karmic,it would boot into w7 without problems.I installed Lucid on another partition,and after that the w7 grub entry would leave me with a blinking cursor in the left top corner, and hang.
I booted with the w7 dvd, ran bootrec.exe to restore mbr and bootmgr, and the booted into w7 to confirm. It was working. Then I booted with the live dvd, mounted the lucid partition, and installed grub. Now choosing the w7 entry would ask for the boot media, and pressing any key would bring me back to the grub menu. Lucid and karmic boot without problems.
Installing grub from karmic now gave the same error. Running update-grub didn't change anything.As I had to use w7, I booted again from the dvd, and restored again mbr and bootmgr. Booted into w7, used it, then once again to the live cd, to reinstall grub, and once again the w7 entry in grub makes grub ask for the boot media.I've attached my boot info script.Ah, I also played with the bootable flag for the /dev/sda1 partition, but it didn't change anything.

menuentry "Windows 7 (loader) (on /dev/sda1)" {
insmod part_msdos
insmod ntfs
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set 3850d16450d12980
chainloader +1
}
This is automaticly genarated after installed ubuntu 10.10. It shows black screen with a flashing cursor after press enter. Grub 0.97 also does this with:
title win7
fallback 2
find --set-root --ignore-floppies /bootmgr
chainloader /bootmgr
savedefault --wait=2
But the wierd thing is my usb stick can boot windows 7 succesfully with the same configuration. Whats wrong with that? How can do with grub.cfg?

I recently installed Ubuntu 10.04 on my dual boot system and noticed that my boot options were changed. I typically have Windows XP as the default OS. Here are the steps that worked for me to get Windows XP as the default boot using Grub2.During my initial Window XP install I had partitioned my hard drive into 3 partitions:
Code:
Partition 1: NTFS format (Windows XP installation) in Linux it is called /dev/sda1
Partition 2: NTFS format (Data for Windows XP) in Linux is is called /dev/sda5

I just installed Ubuntu 10.04 LTS on an external hard drive (USB connected) and I can no longer boot my Windows XP(SP3) from my internal C Drive. Grub gives me the list of boot choices, but when I choose the C drive, I just get these error messages:
GEOM ERROR

Client MAC ADDR: 00 13 D3 07 FD F5 GUID: FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF
PXE-E53: No boot filename received
PXE-NOF: Exiting PXE ROM
(The version of Grub is 1.98-lubuntu5). I don't have a Windows System CD to boot from, but is there something I can do from within Ubuntu itself?

[URL](where loading into Windows corrupts the MBR). None of the solutions in the bug thread work for me, however--I'm on a Dell system (so it's not HP tools) and I'm not running PC Angel or any similar service (I checked). I assume it is related to the Dell recovery partition, though my old laptop from Dell didn't have this problem even though it also had a recovery partition.
However, before I had partitioned and set up Ubuntu on my new laptop, I installed Wubi (for transferring over the files from my old laptop because I didn't have time to do a full install and deal with problems like this one). Wubi worked fine using the Windows Boot Loader. I understand that WBL isn't capable of loading Linux on its own, which is why I was wondering if it was possible to have GRUB installed on a separate boot partition (not the MBR) and loaded from Windows Boot Loader. All of the information I could find on it didn't work with Windows 7--but again, I know Wubi was capable of doing it. how to set this configuration up?

I've currently got a dual-boot setup with Vista and 10.10 (using grub2 on MBR).I'm about to install Windows 7 and would like for a change to use the Windows bootloader. I currently have a separate /boot partition and believe I can install grub2 there so that I can chainload it using EasyBCD.
I'd like to do this from my running system as I don't have a spare USB drive right now. confirm the command I should use baring in mind the separate /boot.If I have to wait and do it from the Live CD - is the command to use any different? FYI here is my current layout:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vg_root-root

I have two hard drives - (1) 80GB (2) 500GB: the 1st HD has 3 partitions (in that order) - Windows 7, Ubuntu 10.10 & Swap. the 2nd HD is for storage only, and has 2 partitions.
I did the following - I installed Windows 7 on the first partition of the 1st HD, it booted just fine. Then I installed Ubuntu 10.10 on the second partition of the 1st HD.
Windows 7 shows in the GRUB menu alongside with Ubuntu. Ubuntu boots just fine, but when I select Windows it simply restarts the computer and the GRUB menu shows again.

Been away from linux for a few years thaught id come back and give it a try again. I have Win7 on sda and installed 11.4 Ubuntu on sdb. Grub2 Over wrote the boot sector for windows so windows wouldnt show in the boot menu. I repaired that after some research and then tried it again with 10.4 LTS version of Ubuntu. Same thing. Now I've fixed windows boot sector a second time and im ready for round 3. Any hints on how to get grub2 to boot both OS's? Ubuntu 10.4 is still on sdb I think I should just need to re-install grub2 But how to do it without Killing the windows boot sector?

I've just installed the 64 bit edition of 9.10 on my workstation. My raid drivers worked without any custom installation, which is very impressive! I am however having a problem installing grub2. I boot to the live CD, run the install process, resize and partition my free space as an ext4 primary partition with mount point /. Everything installs except grub, so I'm always booting in to windows.This seems to be a bit off as I've never had this occur with dual booting before.

I have a Dell PowerEdge SC1425 with two SCSI-disks, that I have tried installing Debian Squeeze on. This machine has previously been running Lenny (with grub 1), and the upgrade was done by booting a live-cd, mounting the root partition and moving everything in / to /oldroot/, then booting the netinstall (from USB), selecting expert install and setting up everything (not formatting the partition).
Both disks have identical partition tables:
/dev/sda1 7 56196 de Dell Utility
/dev/sda2 8 250 1951897+ fd Linux raid autodetect
/dev/sda3 * 251 9726 76115970 fd Linux raid autodetect
/dev/sda1 and /dev/sdb1 contain a Dell Utility, that I have left in place.
/dev/sda2 and /dev/sdb2 are members of a Raid-1 for swap.
/dev/sda3 and /dev/sdb3 are members of a Raid-1 for / formatted with reiserfs.
After installation, grub loads, but fails with the following message:
GRUB loading.
Welcome to GRUB!
error: no such disk.
Entering rescue mode...
grub rescue>
Doing "ls" shows:
(md0) (hd0) (hd0,msdos3) (hd0,msdos2) (hd0,msdos1)
I can do the following to get grub to boot:
set root=(hd0,3)
set prefix=(hd0,3)/boot/grub
insmod normal
normal
This will bring me to the grub menu, and the system boots.
It appears that grub has only found md0, which I believe is the swap partition, because ls (md0)/ returns error: unknown filesystem. I have installed grub to both sda, sdb and md1, and tried dpkg-reconfigure grub-pc and dpkg-reconfigure mdadm, as well as update-grub.
I manually added (md1) /dev/md1
to /boot/grub/device.map, but still no result.
I have run the boot_info_script.sh, but unfortunately I cannot attach the RESULTS.txt, because the forum aparently does not allow the txt-extension. Instead I have placed it here: [URL]. I am tempted to go back to grub-legacy, but it seems I am quite close to getting the system working with grub2.

i wiped my entire hard drive that had xp as its only OS. I freshly installed a Windows 7 ultimate and everything went perfectly. I then decided to install 10.4. I split the partitions correctly (i had experience doing this already with my laptop, which has xp/10.4). Ubuntu 10.4 install went flawlessly, except for one thing. Now when i boot up the pc, it goes straight into 10.4. I have tried holding shift during the start up to force the boot menu, and it just shows the Ubuntu 10.4 OS as choices. Any clue what i could do to make Win7 appear in the boot menu?

I just installed CrunchBang Linux and it's great! But I can't boot into windows anymore. I'm sure it didn't delete my Windows partition-it's mounted. My linux partition is /dev/sda1 Windows is /dev/sda2
Code:
sudo update-grub
Found linux image: ....
Found initrd image: ....
Found linux image: ....
Found initrd image: ....
done
how I can get Windows to reappear? I've had bad luck with Grub in the past and I don't want to fight it on my own...

i finally decided to updgrade from Hardy Heron to Lucid Lynx. for this i made a backup of my old install, then i couldnt find my Lucid CD so i used a Karmic one to partition my old ext3 to ext4. There were some errors but after trying a few times it worked. Installed Karmic, rebooted (worked fine), downloaded all updates - (did NOT reboot to let updates take effect) and upgraded to Lucid.
Everything went fine so far. Now when i try to boot into Lucid the system hangs, i've also got a windowsXP partition on there so i tried booting that, first grub tells me Error 29: Disk write error then trying again windows seems to boot but it takes much longer than it should and seems to hang.
Then i tried Karmic and Lucid LiveCD (which i found in the meantime) none of the LiveCDs make it to boot after about 20 minutes. (previously they worked fine)looking at the errors it seems to be something about the harddrive. Why the harddrive would stop the LiveCD booting is a mystery to me but the same messages appear when i select Recovery from the Grub menu so i guess the problem is related.

I am running a dual boot system with windows 7 and Ubuntu. Both have run smoothly on my machine (Core 2 quad core on Gigabyte board) I recently upgraded to 10.10 from 10.04 via the update manager within 10.04. Following the upgrade the initial boot failed at the login screen ( i simply got the purple colored screen with a white box in the center of it). Instead of trying to figure out what went wrong, I simply re-installed 10.10 from live CD on top of the upgraded Ubuntu that was failing at the login screen. The live CD install seemed to fix everything for the most part ( I did notice some quickly flashing text right before the login screen. I think it was an error message but it was too fast to read)
My problem now is that I am trying to remove some of my old kernels from the Grub2 boot screen and I cant. I have read many posts on how to remove the old kernels, but my system is proving to be difficult. The old kernels definitely show during boot, but whenever I go into Synaptic they are not there. I have downloaded Ubuntu Tweak, and they do not show in it either. I have read the information at [URL] I went to http://www.fixthecode.com/remove-hug...sts-in-ubuntu/ and thought this would fix my problem but I keep getting an error: "awk: 1: unexpected character 0xe2" when i try to run: "dpkg -l | grep ^ii | grep 2.6.3x-xx | awk -F{print $2} I am running kernel 2.6.35-22 The kernels i want to remove are 2.6.32-23 and 2.6.32-24.

I have a netbook running Windows XP as standard. There is also a recovery partition which came from the factory.
In the past I installed Ubuntu (I think 9.something) from USB key and all worked fine. However my XP became corrupted and I needed to do a repair on it. After this, Ubuntu became removed from the boot select menu.
Since then, Ubuntu has become updated to 10.04, which I now cannot install.
The Live CD tells me there is a "file IO error" and simply stops installation at around 70%.
I did manage to get into Ubuntu from a Live USB using Wubi. However when I chose to install Ubuntu to a Harddrive, the option to "install side by side" was missing.
After reading on the forums, I did a chkdsk /f on Windows and tried again. Now my liveUSB does not show a boot menu!
When I select to boot from USB stick, the screen goes blank with a flashing cursor. Ctrl+alt+dlt reboots.
I'm really lost here! It seems when I fix one problem, another problem arises!
Also when trying to instal Ubuntu within Windows, the process goes through to 100% and asks me to reboot. When I do so, the option for Ubuntu does show in the boot menu. However when I select it, I get an error "Windows boot failed: file wubildr.mbr and status: 0xc00000f - something is corrupt".

I upgraded a while back to Windows 7. I run two separate HDDs, with debian on sda and windows on sdb.Everything worked fine, up until i upgraded to windows 7. The installer forced me to unplug sda and make sdb primary. After installing I repositioned the HDDs and was stuck with a "NTLDR is Missing" messageAfter removing the search -fs--uuid tag from grub.cfg, Windows 7 booted for a good 0.5 sec and then rebooted. All that flashed was the "Starting Windows" page. I see similar bugs reported in the launchpad, but nothing that directly parallels this Here's my windows entry in grub.cfg:
Code:
menuentry "Microsoft Windows 7 Ultimate (on /dev/sdb1)" {

I've installed Xubuntu 10.10 on a very new EeePC 1201HA. The netbook came preconfigured from the OEM with the disk split into two Windows partitions of about the same size, one with Windows 7 starter. I removed the second partition (Which was just empty) and have installed a series of different distros since then, to try and gauge their support for the 1201HA hardware. I finally settled on Xubuntu, which can support most of the laptop's features with some tweaks.
However, after this last install, and a Grub config change needed to make the framebuffer work on this hardware, I'm unable to boot Windows 7.Grub shows it on the menu normally, but when I select the Windows 7 entry, I get the message 'Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key,' which I understand isn't from the OS but rather a BIOS message which implies there is no loader.
I've tried using the Windows 7 system restore to do everything short of rewriting the Windows bootloader to the MBR (Which would, of course, remove Grub and thus not solve my problem, as I couldn't load Ubuntu from it). I attempted to fix the boot sector on the partition with the system restore tools, to no avail. And because this is a netbook with no optical drive, I'm unable to reinstall from a disk.

I switched over from Ubuntu because I realized Ubuntu sucks now (lol), but anyways... Now I'm trying to get Grub2 to boot up properly, but this "xputs" error pops up and drops me to the recovery prompt. I tried the grub-install dev/sda and all it did was recognize my Windows 7 OS (as Vista) and added it to the bootloader list and didn't fix the "xputs" issue.
I heard that doing a chroot is the most effective solution. Forgive me, but I don't know what "chroot" means or how effective it is. I can specify more information about where the OS is if needed. I have the boot flag set to the Debian OS at the hd(0,5) or sda5 I think, and Windows is at sda1 (I think). I just want to make sure I can fix this without damaging Windows, and I'll try to get more information.
Right now, I can only get into Windows or Debian with UBCD and Grub2 Super Disk and I know that sometimes Parted Magic could orderly mount the disks differently, so I don't know if it was sdaX or sdbX, but probably sdaX. I'll check again.

I installed Ubuntu in my new notebook. It originally comes with Windows 7 installed on it.Everything works nice however every time i boot into Windows7 the grub menu doesn't work any more. i can't boot into windows or ubuntu any more. How do I stop this? Its rather annoying to have to boot, chroot and fix this problem everytime.
