Boot fails after expanding Win7 partition- just a flashing text cursor
Win 7 is a decent OS when it's running, but the boot process breaks easily and is proving hard to repair.
Some time ago I upgraded my machine from XP to Win 7, but kept XP on the disk in case I needed to roll back. Disk layout-
Partition 1: (reserved for Grub, not currently used)
Partition 2: XP (no drive letter)
Partition 3: Win7 (C:)
Extended Partition: (data partitions)
Windows 7 (partition 3) was the system and boot partition, i.e. there was no separate "system reserved" partition.
After a year or so i decided I wasn't using XP at all, so I was thinking of deleting it to gain some disk space. Then a couple of days ago we had a power failure and the machine started reporting some errors on C:, although it was still booting, so the decision was made.
I made an image backup of the Win 7 partition using ntfsclone from the GParted live CD. I then deleted partitions 2 and 3 and made a new partition 2 to occupy all the available space. I then restored the image of C: into the new larger partition.
Then the fun starts.
I realise that by moving the C: partition I will have broken the link to the start of the partition for the boot process, but I have been through multiple rounds of attempts to fix it and i'm getting nowhere.
Partition 2 is marked with the boot flag.
I have run "system repair" from the recovery environment (from the install DVD) multiple times. Each time it says it has finished successfully, but the boot still fails.
I have also used the manual recovery process from the command line within the recovery environment, including using bootrec.exe with the /fixboot and /fixmbr flags, and re-creating the BCD store.
c:\Boot is present and appears to be correct, but still all I get when booting from hard disk is a black screen and a flashing text cursor in the top left (but this isn't a working command shell).
A clean reinstall of Win 7 with all my applications and customisations is a LOT of work. Am I really lost here, even though I have a full backup image of my C: partition?
Is there a tool that will trace and debug the boot process from a Live CD?
Any ideas much appreciated.
