I bought this computer with Windows XP installed. I removed the hard drive it came with and installed the hard drives from the computer it replaced. That went well except that the Win-XP on the "old" disks knew it had moved and refuses to boot. So this morning I thought I'll install the original drive as a third drive and change grub.conf to fit. That done Win XP will not boot, produces an error message: Error 12: Invalid or unsupported executable format. I can mount the drive in F-14 and list the directory. I took my best guess at the grub designation for the drive: title Windows-XP-Pro rootnoverify (hd1,0) chainloader +1 It had been: title Other rootnoverify (hd0,0) chainloader +1 Fdisk shows the drive details as: [root@box9 bobg]# fdisk /dev/sdc Command (m for help): p Disk /dev/sdc: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders, total 156301488 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc1c1c1c1 Device Boot Start End Blocks Id System /dev/sdc1 * 63 156280319 78140128+ 7 HPFS/NTFS Command (m for help): What am I doing wrong or is Windows refusing to boot because the drive is not where it wants it? Any thoughts/help appreciated.
