I have 3 HARD DRIVES. Drive 1 (sda) is a Windows 7 Drive. Drive 2 (sdb) is a data drive. Drive 3 (sdc) is an Ubuntu 11.04 drive. I just upgraded to 11.04 by disconnecting sda and sdb. I then installed 11.04. I then reconnect all the drives After install I did a sudo update-grub. It displayed the following Generating grub.cfg ... Found linux image: /boot/vmlinuz-2.6.38-8-generic Found initrd image: /boot/initrd.img-2.6.38-8-generic Found memtest86+ image: /boot/memtest86+.bin Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 done I have no idea why 2 Windows. Then ran fdisk -l. It displayed the following Disk /dev/sda: 1000.2 GB, 1000203804160 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xda607973 Device Boot Start End Blocks Id System /dev/sda1 * 1 121601 976759008+ b W95 FAT32 Disk /dev/sdb: 1000.2 GB, 1000203804160 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xda607971 Device Boot Start End Blocks Id System /dev/sdb1 * 1 13 102400 7 HPFS/NTFS Partition 1 does not end on cylinder boundary. /dev/sdb2 13 121601 976656384 7 HPFS/NTFS Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x0009ca99 Device Boot Start End Blocks Id System /dev/sdc1 * 1 120558 968373248 83 Linux /dev/sdc2 120558 121602 8386561 5 Extended /dev/sdc5 120558 121602 8386560 82 Linux swap / Solaris Now when I boot up it shows the grub menu, and lists all the choices, but when the Windows sda1 is picked it reboots. When sdb1 is picked it says I have a windows error. I beleive I have corrupted or destroyed the Windows MBR or Boot Record. I have attempted to fix it using the Windows disk but still does not work. Any help would be appreciated.
