Installing windows 7 after hdd format

Cleaning the disk should force the installer to autostart.

Clean all takes approx 1 hour per 320 gb.

"diskpart> clean all" is still going on. Does it suppose to take this long. A format wouldn't even take this long

lol thanks for telling me that, i have 1.5tb

That's normal.

It can take several hours if you have a 1 TB drive. As much as 5 or 6 hours if you have a 2 TB drive. It is writing zeroes to every sector of the drive.

You said you have a Win7 Installation DVD - it is not a CD which is why I ask - and factory Recovery disks, correct? Or is the Recovery disk actually a Win7 Repair CD?

If you want the cleanest reinstall boot the WIn7 DVD to clean reinstall following these steps to get a perfect reinstall: Reinstalling Windows 7.

The installer should autostart on a wiped HD, however the error you had means the disk wasn't booting and it was trying to boot the HD.

If it occurs again reset the CMOS: Clear CMOS - 3 Ways to Clear the CMOS - Reset BIOS
While in BIOS setup set the SATA controller to AHCI to try install.

Report back what happens including exact text of any error message.

ok so im still haveing the bootmgr is missing

My school let me download a copy of windows vista. I try to install it and when it gets to expanding files i got error 0x80004005. I looked that up and it said to unplug all things that dont need to be plugged in for windows to download. I did that and try to install again and now im getting error 0x80070017. I feel as soon as i look this up and fix this problem i will get another error. Can someone please help me fix my pc.

Did you try wiping the HD as I'd go ahead and do it now if formatting alone doesn't work.

How about clearing the CMOS?

Are all other HD's and peripherals unplugged?

In BIOS setup, set SATA controller to AHCI.

If you have more than 2gb of installed RAM, remove all but 2gb to try install. Next test your RAM: RAM - Test with Memtest86+

Omg I tried almost everything. I put my hd into my bro PC and try to install it and I get the same error. I even put his hdd into my PC. His hard drive tries to boot but then it goes to this blue screen for about .4 seconds and just keeps restarting.

Edit: How do I wipe the hd. If is disk part clean all, I already did that. I will also try removing the ram when I get back home. And everything else you said and I will report back later.

You can try loading up the recovery console and using the "bcdedit" command.

You'll actually need to fix your boot manager with the windows recovery disk every time you are dual booting windows/linux because the grub bootloader takes over the windows one. When you uninstall/delete the linux os, you take grub with it. leaving no boot manager.
