Hi there,
i have a desktop here which won't boot up, including safe mode. It gets as far as the logo then bluescreens: Stop 0x000000ED Unmountable_Boot_Volume.
Startup repair fails and when i boot into Repair my computer it doesn't find any windows installations. Also when i try command prompt i can't access the partition containing Windows so can't run chkdsk.
I tried puting the hard drive in another pc but i can't open it i get a message tellling me it needs to be formatted & Disk Management shows the file system as RAW.
I'm thinking the problem is with the partition table but not sure how to go about repairing it, also would this be correct if windows can boot half way before bluescreening?

I would download the manufacturer's tools for the hard drive (Seagate, WD, Toshiba, etc) and run a diagnostics on the hard drive.  Sometimes (depending on the model of the PC) they have their own diagnostic tools you can use to test the hardware.  Could be just a defective hard drive.

I ran WD Data Lifeguard & it found bad sectors which it repaired & then passed the drive.

you may need to run a chkdsk also

I can't run chkdsk, it tells me the disk is not formatted.

can you boot from the disk?  from your post i guess not

can't you initialise it?
if it does not boot - maybe your best bet is to do a backup and fresh install, from DVD, or from recovery partition

My problem is i can't access the drive to do a backup, which is needed for Outlook .pst files as some are stored in the default folder, C:\Users\Username\AppData\Local\Microsoft\Outlook. All the other files i need are backed up to cloud storage.
Would love to get this back up & running though as there's lots of programs installed which would be a lot of hassle to find & reinstall.
Can i do a repair installation from the windows 7 disk or does it have to be done from a booted windows installation? Seem to remember a problem with that before.

if you only need some files, 2options :
boot from a live cd, like Knoppix, and copy them : http://distrowatch.com/table.php?distribution=knoppix      
or hook your drive to a working system - you may need to take ownership of the files -and copy

both suppose the drive shows in BIOS

I had the drive hooked up to a working pc but i couldn't access the drive, it would tell me it needs to be formatted and the filesystem was RAW.
What i ended up doing was booting to MiniXP on Hirens Boot CD & right clicking the partioition the OS was installed on, clicking properties and scheduling a chkdsk from the tools tab. I then removed the drive & returned it to the original pc & booted up. Chkdsk ran & when it rebooted i got back into windows.
I've now backed up all my files and am in the process of doing a fesh clean install to a new hard drive as i don't trust the old one anymore.
Thanks for all the help & suggestions.
