Thread: Grub2 cannot boot Windows 7 (error 0xc0000225)
i have lucid installed on computer. added second drive, installed windows 7. windows 7 boots fine if drive connected, or selected boot drive in bios. booted lucid, ran 'sudo update-grub' , found windows 7 install on second disk. when try use grub entry boot windows 7, error screen:
i seem remember in grub 1.x days there map command 'swap' drives windows think boot drive, grub2 autogenerated command doesn't have that. ideas on how grub2 boot windows 7?code:windows boot manager windows failed start. recent hardware or software change might cause. fix problem: 1. insert windows installation disk , restart computer. 2. choose language settings, , click "next." 3. click "repair computer." if not have disk, contact system administrator or computer manufacturer assistance. file: \boot\bcd status: 0xc0000225 info: an error occurred while attempting read boot configuration data.
that's interesting. got same failure on w7 install week. think windows update rather grub. had boot w7 cd , repair it.
anyway, have separate disks linux , windows good. best have grub installed mbr of linux disk , not windows disk. you've arranged anyway.
i'd make sure can still boot w7 disk directly. may same error , have repair it.
grub2 doesn't need of mapping stuff. should find windows using uuid these days. key file /boot/grub/grub.cfg (but should not edit it, gets updated update-grub).
