LinuxQuestions.org - [SOLVED] Booting Vista via grub: Invalid or unsupported executable format

Hi

This is about getting grub to boot either FC5 or Windows Vista (on one harddisk). Booting Fedora works fine. When attempting to boot Vista I get this output:

Code:

Booting 'Windows Vista'

chainloader +1

Error 13: Invalid or unsupported executable format

Press any key to continue...

The installation history is as follows:

1) Installed FC5
- no problems with booting
- I had also prepared an empty 80GB partition

2) Installed Windows Vista on the empty partition
- grub menu was gone, could not access Linux anymore
- Vista started up fine

3) Repaired grub and MBR
- FC5 could be accessed again
- Vista could not be booted - my current status

Yeah, by now I know that I should have installed Vista before Linux. But is there any chance to spare me reinstalling the whole system? I have been using FC5 for quite a while, so a lot of configuring and installing has gone into it. As for Vista, I urgently need it working as I must run a piece of software on it.

My configuration:

AMD Athlon 64 X2 Dual Core 4600 on a A8N32 SLI Deluxe board
Fedora Core 5, kernel-2.6.18-1.2257.fc5 (x86_64)
Windows Vista Beta 2 x64

My partitions (as reported by parted):

Code:

Model: ATA ST3250620AS (scsi)

Disk /dev/sda: 250GB

Sector size (logical/physical): 512B/512B

Partition Table: msdos



Number  Start  End    Size    Type    File system  Flags

 1      32.3kB  107MB  107MB  primary  ext3

 2      107MB  168GB  168GB  primary              lvm

 3      168GB  250GB  82.2GB  primary  ntfs        boot

Mounting point of sda1 is "/boot". The logical volume group on sda2 contains two logical volumes ("/" and swap). Obviously, sda3 contains Vista.

My grub.conf looks like this:

Code:

default=0

timeout=30

splashimage=(hd0,0)/grub/splash.xpm.gz

#hiddenmenu

title Fedora Core (2.6.18-1.2257.fc5)

        root (hd0,0)

        kernel /vmlinuz-2.6.18-1.2257.fc5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet

        initrd /initrd-2.6.18-1.2257.fc5.img

title Windows Vista

        rootnoverify(hd0,2)

        chainloader +1

Plan B: If there is no other way than reinstalling everything, is there something I should be aware of other than the order of installtions?

Thanks so much for any hints!
