Acronis cleanup utility tool caused system to crash to BSOD which is so far unrecoverable

I downloaded the trial version of True Image Home 2011 but it would not install, citing errors.

There were no entries in the Windows program list to indicate any trace of previous versions and after doing a little research I discovered that there was an Acronis cleanup utility tool to remove any old traces.

I subsequently used the tool successfully but on reboot received a BSOD just as the 4 coloured windows logo squares were coming together during the start-up screen:

STOP: 0x0000007B (0x80786B58, 0xC0000034, 0X00000000, 0x00000000)

The machine had been working perfectly for months prior to this and I am confident that there was no virus of any kind.

One suggestion was to modify the BIOS to turn off ACHI and move to IDE for the SATA boot.

This only allowed the 4 coloured windows logo squares to come together before creating the same BSOD.

I ran the Windows 7 recovery disk which attempted to repair the Boot menu but on subsequent boot the same issue arose when booting into Windows normally.

I additionally used the inbuilt Windows repair option available from the boot menu but this just returned error 0xC000000e The boot section has failed because a required device is inaccessible.

I've used the Windows 7 recovery disk to use a system restore point but this did not change anything.

Last thing I tried was to use bcdedit to recreate the boot file using the instructions here
http://support.microsoft.com/kb/927391 but was unable to correct the issue.

Can anybody advice further as I really don't want to have to re-install Windows as it has taken me weeks to get the configuration just right.

Also, does anybody know exactly what the removal tool removes?
