I did not try the chkdsk thing but did you boot from a windows cd to run it?
By design, the last sector of ntfs is a backup of its boot sector. By copying the last sector to its first sector I successfully recovered the NTFS file system on my memory stick. There's no operating systems on the memory stick so I don't know if this recovery method can fix the boot issue of Windows. ( If boot sector is the only sector destroyed it is expected to fix the boot issue but unfortunately several sectors are overwritten ) I would appreciate it if you could test this for me: First check if FlexNet is still there ( Earlier versions of grub2 overwrites it) sudo dd if=/dev/sda count=63 2>/dev/null | hd | grep "d8 41 a0 f5 02 00 02 00" If the command above returns nothing it's gone. If it finds FlexNet, try ruin your C drive by installing grub2 from 11.04(backup your data first of course): sudo grub-install /dev/sda You will see a warning "Sector 50 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track." Then run "sudo parted -l", if the file system of sda1 is not shown you successfully ruin your C drive. Now run "sudo fdisk -lu", from the file you attached its output was Device Boot Start End Blocks Id System /dev/sda1 * 63 85160564 42580251 7 HPFS/NTFS /dev/sda2 85160626 1953520064 934179719+ 5 Extended /dev/sda5 85160628 419441084 167140228+ 7 HPFS/NTFS /dev/sda6 419441148 461386799 20972826 83 Linux /dev/sda7 461386863 1846141604 692377371 83 Linux /dev/sda8 1846141700 1953520064 53689182+ 7 HPFS/NTFS If the partition layout has not been changed since then, recover the boot sector of sda1 from the backup sector: sudo dd if=/dev/sda of=/dev/sda count=1 seek=63 skip=85160564 Be very careful here no to type anything wrong. Both "if" and "of" devices are /dev/sda, not /dev/sda1. And if the start or end sector changes, modify seek="start sector" skip="end sector" correctly. Now /dev/sda1 should be mountable again. Reboot to see if windows boots.
