Can't install Windows 7 Home Premium 64Bit?

Sheesey · 15 Nov 2011

Basically I'm ready to explode. As you know, I'm running Ultimate. I recently decided to upgrade to a 64 bit OS. I purchased a 250 gb harddrive for it. (dualboot 32 bit and 64 bit win7) but my ISO file won't boot. I've tried everything. Yes, my PC is 64bit capable. Please help me.

P.S I don't have any spare flashdrives as they like breaking. And, sadly, no spare discs for a week. I can't eve partition because of some stupid disabled thing.

Thanks in advance, Rangi.

You say you've tried everything, but that doesn't tell us what you've tried. :)

Did you download another ISO?

Did you try a slower burn?

Have you set your BIOS to use the DVD drive as the first boot device?

What exactly do you mean by your USB flash drives keep breaking?

If you do have a bad burn or a corrupted ISO, then really you're screwed until you get some more blank discs.

What I meant by that is all my flashdrives are broken. I'm trying to boot from the iso using poweriso 4.7. It just wont show up in boot menu and bios.

If your flash drives are defunct, you do need to get hold of a blank disc and burn the ISO to it then insert the disc, restart your computer and boot into it.

You can't just download the ISO to your hard drive and boot from that, it has to be burned to a disc first.

Buts that's how I installed Ultimate over Vista. It should work as easy as last time.

You currently have Windows 7 32-bit.

You want to install Windows 7 64-bit.

You CANNOT upgrade from the 32-bit version of Windows to the 64-bit version - it HAS to be a clean install.

For a clean install of Windows 64-bit, you need a either Windows 64-bit DVD, or a Windows 64-bit ISO that has been burned to create a bootable disc, or a bootable flash drive.

As you don't have a Windows 7 DVD, a working flash drive or any blank DVDs, you are up the proverbial creek without a paddle.

To dual boot, you need both the 32 and 64-bit versions of Windows.

Okay, I'm sorry for the very small posts. I was using a cellphone.
Here's what I meant in more detail. I have Windows 7 Ultimate 32-Bit running on my C: Drive and that was installed via ISO. I currently want to install Windows 7 Home Premium 64-Bit on my secondary Harddrive. (They are both separate hardrives not partitions.) As it won't boot (Like the Ultimate ISO did when I had vista) I can't install it on my other Hard Drive. I have a Vista disc which I tried to install onto my other Hardrive (So I could clean install over it) but when I try to boot it (Even with temporarily disabling my main HD by disconnecting cables) it shows me the error "Error loading Operating System"

I'm sorry for the inconvenience I caused you.
Rangi.

I'm still totally confused.

Do you or do you not have a Windows 7 64-bit DVD?

If not, do you have the 64-bit ISO burned to a DVD?

If so, disconnect the drive with Windows 7 32-bit on it, and then try and install Windows 7 64-bit to the other drive.

If you can't, you have a bad disc or a bad hard drive.

I do not have a DVD no. It was purchased online as an ISO. I currently don't have any discs. Poweriso let me boot my Ultimate 32-bit Iso from PC startup. Why won't it work now. Is there any way of doing this or will a virtual flashdrive help? (For startup)

seavixen32 · 16 Nov 2011

From what you are saying then it would appear that Poweriso is compatible with Vista, but not Windows 7.

Have you tried installing it in compatibility mode for Windows Vista?

Failing that, you need a blank DVD to burn the ISO to.

As for a virtual flash drive, I would imagine Google is your best bet.
