Windows 7: MBR error on reinstalling Win7 to clean HD

You're the lead here Greg. I just want to make a comment.
My ASUS motherboard definitely does not have CSM/Legacy BIOS options since I believe later UEFI firmware may have done away with this need. What if the destination HDD is preformatted GPT - what do you think?

(BYW I stick with MBR boot)

Normally deleting all partitions will allow installer to change format to what is set in BIOS. But it may take wiping with Clean command.

There should be a way to change to/from Legacy on most every mobo but it may be hidden or tricky, even require a firmware Update.

If you'll post back screenshots of BIOS settings choices we can all look together as an exercise. I once found it under Reset to Defaults instead of Reset to Windows 8 Defaults.

Mine is the same BIOS version, 2-10-1208, AMI. There are no CSM nor Secure boot options as mjf said.

While I had the USB stick in my BIOS also shows it as "UEFI Patriot Memory" although I don't use it.

Gary wouldn't there need to be a Windows Boot Manager or Hard drive listed as one of the Boot order items? He only has the stick listed as first boot device, none others.

Yes, I just noticed that, only the Stick is attached.

Beanster, when Greg said remove all other drives, he meant remove all other hard drives EXCEPT the one you will install w7 on.


Did this PC have a factory install of Win 8? Did you build it?


Do this the best you can with exact brand and model numbers.

To better help us to help you would you please add your systems specs? Here's the correct way to do it. :SystemInfo See Your System Specs Under System Manufacturer/Model Number add whether it is a desktop or laptop and whether self built. Very important

Log in to Seven Forums and you will be able to transfer the info directly to the specs page in your profile from within the System Info app.

Your System Specs here.

After doing this your specs will be available in each of your posts.
Click on My system Specs in the lower left of this post to see how it should look.
Full instructions are in the tutorial.

He probably had the hard drives attached at that point, but one was not chosen. I have not seen the need to select Windows Boot Manager or EFI Boot Manager before when installing to UEFI, assuming the installer did it for you, but it does end up being what's listed in BIOS after a UEFI install - whereas with an MBR install it is the HD itself which is listed as the OS boot device.

Perhaps this is what's generating an error message that he's attempting to install to an MBR disk, since UEFI Boot manager is not selected in BIOS to assure formatting of disk as GPT. It's just a guess but I thought I'd put it out there.

Good calling for specs so the mobo can be thoroughly vetted. Often when I run into these problems I find that others have asked google about the problem for their board or PC model.

I thought that was what I was suggesting. However, if the disk was unallocated then I wouldn't expect an installation error message.
@Beanster
try installing to either an unallocated or GPT formatted drive.

I'm gathering my specs manually, just so y'all don't think I died. I have no access to internet on the pc, so I cannot download that file. Still, I have the required info, just need to find my purchase paperwork and transfer the info. Thank you so much, Gary, for showing me the link on my own profile so I can populate it manually. I'll post when it's done.

Did I miss the post where the SSD was initialized GPT or MBR?

I saw it cleaned, but

Sorry to interrupt... carry on
