My laptop has a good ol i5 9300H and a GTX 1650, along with 8 GB of ram and 16 GB of intel optane memory.

My problem is, I'm trying to dual boot Ubuntu and windows 11 on it, i made the usb as such and all but when i use the usb to install, it tells me intel optane is turned on and therefore i need to turn it off.

I find the setting in bios, disable it, but now i can't boot to my windows 11 (INACCESSIBLE BOOT DEVICE), but the GNU GRUB does come up.

My questions:

1. How will I get back to the windows 11 hard drive? While it doesn't have much that can be lost, I'd rather not try to install all the drivers and stuff again.

2. If i install Ubuntu now, would that wipe out all of my windows 11 and files?

3. Do i need to remove the intel optane memory? Will it be solved then?
