Installation problem

UEFI installed OS can only boot from a Partition formatted to FAT32.

Post 64
UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

Partitioning in diskpart.

First of all, let me thank you guys for all the help so far. Also thanks for the tutorials and the youtube link. Those are very informative.
I want to assure you that I am reading and studying for all I am worth, not just leaning on you guys.
Also, I shall stay with this project until it succeeds or the computer bursts into flames.

Greg,
fwiw, the win xp partitions look normal to me, and the xp boot files are present in the OS partition. Does the C: partition look normal to you?
As to installation, I think that the installation from the factory disks is pretty much automatic, and no option is offered for UEFI or Legacy.

Theog,
This BIOS is a UEFI type, but that Secure Boot screen in post 19 is not available.
On the HP page cited in post 19, go to: Security Menu > Secure Boot Configuration
There is a note that says:
NOTE: This option is available only with BIOS 8 and on computers with Windows 8 installed.

Also, The only thing I don't remember on the win 7 disk is that 128 mb partition called "Other". It may be normal, I don't know and don't remember seeing it before. I don't have a screenshot of the HDD before this problem started.

I have a tentative plan. Let me know what you guys think, especially if there are any bombs I have overlooked.

Before starting, though, one question: Can you guys think of any reason why creating those new partitions on the win xp HDD would cause the win 7 computer to go to it first, and apparently mess up the win 7 boot manager? Remember that it was not attached to the win 7 computer when the partitioning was done. And that is the only change I have made to either HDD.

OK, heres the plan:
1st, use Partwiz to combine the 3 new partitions on the win xp hdd into one extended partition formatted NTFS. Leave the C: partition alone.
- try to boot from the boot menu. If no go,
2nd, restore this BIOS to defaults using the available screens in the BIOS itself. AN HP helper said that that option restores the BIOS to its original state. That state worked with both win 7 and win xp from the one time boot menu.
- try to boot from the boot menu. If no go,
3rd, if these efforts fail, reinstall win 7 from the factory disks, then reinstall win xp from the .iso disk I used initially. Greg, I read your tutorials and they are really good. However, I am content to just reinstall from the factory disks and endure the HP bloatware. Its just quicker/easier, is all.

Can you take a screenshot of CSM in the BIOS.

What

Well, not really work. . . : - ) I was getting that picture loaded up to photobucket.

And you cannot get XP HD to boot choosing Legacy HD,

or Win7 HD to boot using Windows Boot Manager?

Are they plugged in exactly as they were when it worked before, and could you then let one boot by default but trigger the other using the Boot Menu key?

If it`s Win7 that won´t boot correctly after repartitioning XP it makes me think there´s a BIOS setting problem since nothing on the XP HD was involved in booting Win7. It could also be a cable.

You don´t need to waste time with Photobucket - just use the paper clip in reply box to attach.

We sometimes see boot code interfere with another HD´s boot. The way to troubleshoot this is to unplug the suspect HD. If the HD will boot, or can be made to boot via repairs, then the solution in that case is to wipe the blocking HD with Diskpart Clean Command to clear the boot sector. This will wipe everything off, though, requiring reinstall.

Repartioning the XP HD can sometimes scramble the boot sector if the resizing is done on it´s area. So its possible this is the problem.

But a more likely cause is the strange Dual Legacy/UEFI boot and priority menus which I´ve not seen before. Something in one of the settings may be awry. Did you try resetting to Defaults? Note all settings first.

If I unplug the win xp hd, then perform startup repairs, the win 7 hd will boot OK, just a bit slower, until the next time I plug in the win xp hd, after that I must perform startup repair again to get to win 7.

No, have not tried resetting yet.
Strange indeed. Copyrighted by HP and American Megatrends, so it's proprietary, and really ornery.

What do you think of the plan in post #22?
