Windows 7: booted into old install of windows 7, help please

booted into old install of windows 7, help please

I was running 32bit windows 7 and ran into a bunch of problems so I installed the 64bit version and everything was running great then all of a sudden the computer turns off, it was similar to a blue screen except there was no blue screen. My computer restarted and when I logged back in it was the old 32bit version from before, I thought a fresh install formats the drive? How can I get rid of this 32bit version and log back into the 64bit version, there's no dual boot option if that's the case. Any help would be appreciated, thank you.

Hello thefabman, welcome to Seven Forums!

Before we make any specific recommendations will you please post a snip/screen-shot of the entire disk management drive map with a full description as to which drive/partition is which, so we can see what you have going on as there may be a fairly simple way to resolve the situation.

In the Windows start menu right click computer and click manage, in the left pane of the "Computer Management" window that opens click disk management and post a snip of that.

Use the Snipping Tool in Start Menu.

Maximize the Disk Management window, include listings and full drive map of HD's.

windows 7 home premium 64bit

The main drive is C: here but in the 64bit version i installed the main drive became R: and i believe the E: drive from this snapshot became C: i tried to change the drive letters but it wouldnt let me change the E: drive from this snapshot, the main drive in the 64bit version i could change the drive letter, i dont know if that has anything to do with anything. It's almost as if the drive unformatted itself because nothing from this 32bit version was in the windows.old folder, it erased everything so unless my computer had a quantum moment and time traveled im completely clueless as i dont have a quantum core processor.

Windows 10 Education 64 bit

What procedure did you follow when you did the 64 bit install?
Did you boot from the windows 7 DVD?
Did you select the correct drive to install too, the one that had the 32 bit version on it?
Was that drive 0?
Did you format the drive and or delete any partitions during the install?

If you installed 64 bit to another HD, it placed the System boot files on C and configured a Dual Boot.

If you're booted into C and that's your original 32 bit then I'm guessing 64 bit is now DISK0 F - the description given is incomprehensible.

You can never change a drive letter for an OS partition as it will destroy your installation.
If you want to try to boot F then change it back to whatever drive letter you changed it from.

Then unplug C, set F as first HD to boot in BIOS setup (after DVD drive), boot the 64 bit DVD, select Repair my Computer on second screen, accept any offered Repair. If Win7 doesn't start, boot back in to Startup Repair - Run 3 Separate Times until it writes the System boot files to DISK0 and starts up.

If 64 bit starts up, you can plug back in C and boot it using the one-time BIOS Boot menu key - delete any useless Windows Dual Boot menu in msconfig>Boot tab. You can wipe C using Disk - Clean and Clean All with Diskpart Command

Booted from dvd, whenever I do an install I disconnect my other two drives, they're ide drives, my main drive is sata, it was drive 0. Its not possible that it installed on the other drives because they weren't connected, I really don't know why the drive changed from c: to r:

OK so why do you think you are now back in the 32 bit version? Hit the Windows key and the Pause/Break key. (For system type what does it say?) Then go to Advanced system settings. Click the settings button under Startup and recovery under the advanced tab. Remove the check mark for Automatically restart in the System failure section. Now instead of rebooting you should see the actual BSOD, if it happens again.
