Ubuntu Installation :: Grub2 Won't Boot The Windows

May 3, 2010

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.

Ubuntu Installation :: Grub2 Cannot Boot Windows 7?

Dec 10, 2010

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?

Ubuntu Installation :: 10.04 / Windows XP Dual Boot (using Grub2)?

May 12, 2010

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

Ubuntu Installation :: Fixing Grub2 Boot Changes To Windows Drive?

May 3, 2010

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
For Realtek RTL8139(X)/8130/810X PCI fast ethernet controller v2.13 (020326)
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?

Ubuntu Installation :: Windows Boot Loader And GRUB2 On Partitions

Aug 20, 2010

[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?

Ubuntu Installation :: Grub2 Onto /boot In Prep For A Windows Upgrade?

Apr 9, 2011

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
37735960 15719388 20099644 44% /

Ubuntu Installation :: Windows 7 Shows In GRUB2 Menu But Won't Boot?

Apr 13, 2011

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.

Ubuntu Installation :: 11.4 - Grub2 Kills Windows Boot Sector

Apr 30, 2011

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?

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?

Ubuntu Installation :: Windows 7 Dual Boot Grub2 Doesn't Install

Apr 26, 2010

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.

Ubuntu Installation :: Grub2 Doesn't See Windows 7 - Doesn't Appear In Boot Menu

Jun 10, 2010

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?

Ubuntu :: Grub2 Won't Boot Windows 7?

Oct 27, 2010

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:

Ubuntu :: Grub2 Won't Boot Windows 7 ?

Nov 18, 2010

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.

Debian Configuration :: Use Grub2 To Boot Windows XP

Mar 28, 2010

how to use Grub2 to boot Windows XP and Linux.

[code]...

there were no entries in the Grub 2 menu after booting. I don't really understand the numbering of hd0,0 to like sda, but I changed "root (hd1,0)" to "root (hd0,0)" if Windows is on hd0, but after rebooting, I still didn't see it. I read somewhere that Grub2 starts partitions at 1, but wasn't sure that was true because in menu.lst they start with 0 sometimes. know entry-level steps to solve this?

Changing ${root} to (hd1) makes no difference. Also, I've been using Windows 7 for moths now without a problem, it's only when I try and boot it form grub2 that I get a problem. Physically removing sda lets Windows 7 boot fine.

General :: Make Grub2 Boot Into Windows 7?

I had Windows 7 installed on my system, then I installed Debian testing with grub2 as its boot manager.Initially I couldn't see windows entry in grub at all, so I ran:aptitude install os-prober kcpuload update-grub Now I can see the entry, but when I select it I get only Win7 system restore, instead of the the real thing. Any ides how to make it work?

EDIT: I tried the suggested approach to add a new file to /etc/grub.d, which generated an entry in grub.cfg, but it does not appear in the grub menu on boot :(

I have this:
grzes:/home/ga# cat /etc/grub.d/11_Windows
