Windows 7: UEFI boot keeps changing; UEFI/Win7 handshaking confusion

UEFI boot keeps changing; UEFI/Win7 handshaking confusion

Trying to understand handshaking between UEFI & Win 7. Have Windows 7 Pro sp1 64 installed on SSD, mb=Asus F2A85-V Pro. Example: boot to flashdrive to do Acronis backup of SSD; remove SDD, insert spinner; boot again to flashdrive to do Acronis restore to spinner (to test backup); remove flashdrive, boot to UEFI, set UEFI spinner as default, save & reset; spinner starts boot (#1), Win logo shows briefly, reboots (#2) and shows Win repair/normal screen; choose normal; Windows desktop shows; new driver is loaded for spinner and asks for reboot (that part I understand); reboot (#3) starts and again briefly shows Win logo before yet again rebooting (#4) to the Win repair/normal screen; again choose normal & all is happy. But then I remove the spinner, insert the SSD, and have to go through the whole deal again. Why so many reboots?

Similarly, if I change any hd/flashdrive configuration, my UEFI boot selection is lost & I have to reset it again - sometimes with the multiple reboot scenerio, sometimes not. Sure wish I could force that the UEFI selection stay there as long as the selected drive is installed.

Hello and welcome diana look I am having a little difficulty in following the train of the thread.

Now do you mean you just backed up the SSD to a USB stick ? then tried to transfer that USB stick back up to the spinner? If it was just a back up then I don't think it is going to work because it is only a backup.

To make the spinner the boot device I would be cloning the SSD to the spinner. I wouldn't mucking around with sticks as I cannot see why that is necessary.

I understand your frustration which is why many users not ready to mess with UEFI BIOS are choosing to Bypass UEFI to Install WIn7.

ICit2lol, the flashdrive is just a bootable with the Acronis software. Don't like doing system backups from a live system. Scenerio is: boot to the flashdrive to back up the SSD to a "backup" HD, remove the SSD, add the "test" HD, boot from the flashdrive to restore the backup image from the "backup" HD to the "test" HD, remove the "backup" HD & flashdrive, reboot with only the "test" HD to verify. Sorry I didn't make it clearer in the orig post; was trying too hard to show the multi-boots.

gregrocker, I do realize that there are a lot of pains with UEFI and that it is much easier to work with the tried-and-true BIOS/MBR. But the new preloaded systems are coming out UEFI-style, so I need to learn how to deal with it. Case in point, I've got a new laptop that I want to explore before deciding if there's too much crapware and I want to rebuild from scratch or to just remove the unwanted software.

I've found a fair amount of info on UEFI itself, but not much on the UEFI-o/s interaction. Don't know right now if the symptoms I'm seeing are "standard" or ASUS/Windows 7 specific.

As Windows Boot Manager is always first boot device, every time you change HDD/SSD, the UEFI/BIOS firmware will reset.

theog, think I've read/viewed all of your listed links earlier except the "UEFI and Windows" which I will check out when I go to a Windows 7 box (on XP with Office97 now & it doesn't read that format). What I haven't seen anywhere (at least in a form that I understood) is that

I'm assuming typo "very" meaning "every". That explains the symptoms. What a pain. But the UEFI boot is fast when you're in a static drive situation. Thanks.

Edit: Can't believe this is my first post. Been lurking here for years & didn't realize I hadn't registered. Thanks to so many for all the tips I've used.
