Bug#623683: grub-pc: grub2 and Windows 7 infinite reboot loop

[Christoph Pleger]

Package: grub-pc
Version: 1.98+20100804-14
Severity: important

Hello,

on my computer, Windows 7 cannot be booted if grub2 is installed as
bootloader. Everytime when I choose Windows 7 in the boot menu, Windows
starts to boot and shows its animated boot logo, but after some time,
probably when normally the graphical login screen appears, the computer
reboots.

I have two harddisks in my computer, one IDE and one SATA. The first disk
(IDE) has the following partitioning and bootloader configuration:

/dev/sda1       active partition, 64 MB, ext3, Mountpoint /boot for Linux
/dev/sda2       25 GB, FAT32, old Windows 98 partition
/dev/sda3       100 MB, NTFS, system partition for Windows 7
/dev/sda4       250 GB, NTFS, installation partition for Windows 7

The bootloader is installed on /dev/sda1, not in the MBR of /dev/sda. The
MBR just contains the standard bootloader which simply boots the active
partition.

My grub2 entry for Windows 7 looks like this:

menuentry "Windows 7 (loader) (on /dev/sda3)" {
        insmod part_msdos
        insmod ntfs
        set root='(hd0,msdos3)'
        search --no-floppy --fs-uuid --set aa743df4743dc3bb
        chainloader +1
}

This is not the same bug as #561154: Removing the line "search --no-floppy
--fs-uuid --set aa743df4743dc3bb" does not help.

The equivalent configuration (partitions, location of the bootloader and
menu entry) works fine with grub-legacy.

Regards
  Christoph
