I have a dual boot laptop with debian stable & Windows 7.
The HD partitions are:
sda1: NTFS for W7
sda2: FAT32 (currently unused)
sda3: linux /boot
sda4: linux ext4, which is LVM with encryption
I've re-installed W7 and now need to recover the MBR & grub menu.
I've booted with the netinst usb in rescue mode, but it fails to mount the root partition /sda4:
"An error occured while mounting the device you entered for your root file system (/dev/sda4) on /target"
and /var/syslog shows:
rescue-mode: selected root device '/dev/sda4'
umount: cant umount /target: Invalid argument
isofs_fill_super: bread failed, dev=sda4, iso_blknum=16, block=32
EXT2-fs (sda4): error: unable to readsuperblock
EXT3-fs (sda4): error: unable to readsuperblock
rescue: mount: mounting /dev/sda4 on /target failed: Invalid argument
So it seems like something is wrong with the mount command?
Would appreciate suggestions how to solve this.
