hopefully it does not nuke my other drives, I've selected keep nothing

thanks again

Might want to disconnect your other drives....

Have you tried using advanced options and deleting all partitions until everything says unallocated. Then use the 'NEW" button. It should create all new partitions and then you should be able to install.

Disconnect 1 wire from every drive except the ones Windows is to be installed on.

the only options I see are format, which it has done, delete, and several info types, there is nothing left, no advanced option, even if i select the other partition on the raid1.

one would think MS would have foreseen something this basic as to check the drive type, and its partitions and flag the user.

what a massive waste of time just trying to get an install that will remain stable, all the problems began with an update one fine morning ........

now I have to figure out how to change the c drive partition type

You can try booting to Kyhi's rescue media, which has Aomei Partition Manager on it.

When you booted into the USB installation disk, which entry did you select? There should have been 2 for the USB, one would have been the name of the USB and the other named UEFI name of USB. Try booting into the one with just the name of the USB, not the UEFI name.

If it said you have an MBR drive, then your drive has a legacy install which means you need to boot into the NON-UEFI name. I am guessing you selected the UEFI flash drive name, which means it is trying to install in UEFI mode, but can't because of the disk partitioning style.

I'm glad you have it working again.
