Hi all, First of all many thanks to Alexander Dalloz for answering the question about multiple logical network devices which enabled me to get this laptop running at home now. I'll provide some more information about the system which can't boot WinXP. I install grub as normal. Here's my grub configuration: (root@localhost:~)# cat /boot/grub/grub.conf # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,6) # kernel /vmlinuz-version ro root=/dev/hda10 # initrd /initrd-version.img #boot=/dev/hda default=0 timeout=5 splashimage=(hd0,4)/grub/splash.xpm.gz hiddenmenu title Windows XP rootnoverify (hd0,0) chainloader +1 title Fedora Core 3 (2.6.10-1.770_FC3) root (hd0,4) kernel /vmlinuz-2.6.10-1.770_FC3 ro root=LABEL=/ rhgb max_scsi_luns=8 initrd /initrd-2.6.10-1.770_FC3.img And the harddisk looks like this: (root@localhost:~)# fdisk -l /dev/hda Disk /dev/hda: 60.0 GB, 60060155904 bytes 255 heads, 63 sectors/track, 7301 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 1275 10241406 7 HPFS/NTFS /dev/hda2 1276 7300 48395812+ f W95 Ext'd (LBA) /dev/hda5 1276 1288 104359+ 83 Linux /dev/hda6 1289 1798 4096543+ 83 Linux /dev/hda7 1799 2104 2457913+ 83 Linux /dev/hda8 2105 2359 2048256 83 Linux /dev/hda9 2360 2499 1124518+ 83 Linux /dev/hda10 2500 2550 409626 83 Linux /dev/hda11 2551 3825 10241406 7 HPFS/NTFS /dev/hda12 3826 7300 27912906 b W95 FAT32 It' s my friend who partitioned his harddisk and I've no clue to what he did to the latter--- He might have partitioned the whole thing wrongly. I just installed FC3 in it and partitioned the empty space for Linux. As for his windows stuff I' ve also no idea but it did boot beforehand. Everything is just normal install. I didn't do anything fancy. Thanks for the help. -- Cheers, Didier. ------------ Didier F.B Casse | PhD candidate | LiMiNT Beamline Singapore Synchrotron Light Source (SSLS), 5 Research Link, Singapore 117603 Email: elprodigioREMOVE_THIS_ANTISPAM_MOJO@xxxxxxxxx| Web: http://ssls.nus.edu.sg | GPG Key 1024D/B3C57D01 2004-06-23 On Apr 2, 2005 10:59 PM, Alexander Dalloz <ad+lists@xxxxxxxxx> wrote: > Am Sa, den 02.04.2005 schrieb Didier Casse um 16:53: > > > Now grub can't boot my friend's windows xp and complains: > > > > Error 13: Invalid or unsupported executable format > > > > I roughly know what it is but I want to know how to solve this.
