OK- I have tried hirams boot disk and tried fixing the MBR.
That allows it to start windows 7 but as soon as it starts it says it detected a fault and the black screen gives the option to run the startup repair tool. I tried system restore but it failed the only restore point (an update)
I tried start up repair but it didn't work
I tried memory diagnostic- no difference (it boots up on a linux CD anyway so memory is probably ok- it seems like the boot hard drive is the issue).
I tried command prompt and chkdsk /f ... had to dimount the drive as it requested, the it reported no problems.
After all the options the only one left is to restart- back to square 1
I tried a windows 7 cd and ran the repair installation but it couldn't start properly either.
It now shows a "windows boot manager" screen at start up and gives the option to start windows 7 or windows 7 professional (recovered).
If i choose windows 7 it does the same restart thing.
If I choose windows 7 (recovered) it shows a menu for start up options (safe mode etc.)
Whatever I choose here it simply loads the files for a few seconds then the screen shuts down and the bios splash screen appears agin and its back to the windows boot manager screen. If I don't choose within so many seconds it starts up anyway and -flash- back to thje bios splash screen( it says Sager) then the boot manager.
I'm afraid I am busy at work so I had it running to the side of me so couldn't monitor all the screens. It has restarted so many times I couldn't keep track. At one time I managed to get an option to NOT restart on errors (maybe that was the Windows CD) so I chose that and the next start showed a blue screen. Since then it hasn't shown up.
Hirams boot disk again- I tried mini windows xp and it starts like this and gives a desktop.
I can see the drives in my computer.
I attached a USB disk and copied the files to it but hey may not be of any use without the machine running again.
There is a system drive (C

and WIndows drive (D

I looked in the C: (system drive) and among the files there is bootmgr, BOOTMGR.BAK, IO.SYS, MSDOS.SYS. The file named BOOTSECT.BAK will open in notepad++
some of the english text there says "a disk read error ocurred; BOOTMGR is missing; BOOTMGR is compressed.
I never saw these messages in the start ups. Don't know what this means.
The Windows drive has the program files and other folders.
In device manager the only disk I see is Volume0 and it says manufacturer unknown
In disk manager I see disk 0 with two partitions (C: System -Healthy active) and (D: Windows healthy)
In the BIOS I see two HItachi drives on SATA ports 1 and 2.
In the boot sequence tried moving the second HDD from 6 up to 2 and booted- I saw ablue screen flash briefly then back to square 1- restart.
So nothing seems to get past this so far.
