Windows 7: E: drive formating problems, system prevents full space wanted

E: drive formating problems, system prevents full space wanted

hey guys so recently i cant use my other drives E: with out it crashing as I log on
(2 bootable drives)
C: Windows 7 Home premium, 64bit
E: Windows 7 Home premium, 32bit
so ive decided to format the HDD since Its useless to use, but unfortunetly it says "Windows cannot format the system partition on this disk", please be aware I'm very new to computer hardware and software and features, I just want to use the drive as spare space for movies, music, games. nothing more than a fresh space for such and such. I require full detailed discription on how to fix this problem with out having to pull apart the computer. at this point I am unaware if i can use system restore from the boot but may be able to. this has nothing to do with C: drive for i want my main drive untouched and/or unharmed

I can provide screenshots of where I am if needed and what to do next. thanks :)

also another thing to know ive only just recently started Tafe on IT so of course i know only limited amount of my computer so far.

You would need to boot with drive C: Then you should be able to re-partition and format drive E: You can't format the drive that you're booting from.

That is, if I read your post right. I may have misunderstood.

Try disconnecting one of the cables from the drive you want to format and try to boot. I believe you will find it won't boot as it is listed as the system drive. Get your repair disk you made or the installation DVD and run startup repair 3 times with attempted reboots in between each. Startup Repair

If that does not work, try Bootmgr is missing - Fix

Exactly as Essenbe said, but just to clarify: run Startup Repair with the E drive disconnected.
Startup Repair will create and install the System files you need to boot on the C drive.
Once the C drive can boot and startup Windows on it's own then you can delete the E partition and format the drive.
