I uninstalled Intel Optane Memory, believing that would interfere with making a dual-boot system with Linux on a Lenovo Ideapad i7 (based on a guide). There was a warning message about potential data loss, and a check box to read about it. I checked the box, and selected next. The text file says my system will be unbootable after a re-start. The application uninstall proceeded at the same time it opened the text file. (!!!)

I had made a restore point just before initiating that uninstall. The uninstall window is still waiting for me to initiate the restart. I have made two backups of all my data (not the OS stuff). I really don't want to have to reinstall Windows, and Office, and all the licenses, etc., etc. The computer didn't come with a CD/USB with the OS. I realize I can download Windows - I'd have to research how to do that. This is a one-year-old computer that came with Windows 10 (not Office). (I do have Ubuntu on an external SSD, and it has grub on the SSD, not my internal hard drive, so that should still boot fine. I actually made that install with the internal drive physically disconnected.)

Can I undo this? Can I restore to that restore point right now?

Any help is greatly appreciated.

UPDATE It looks like if I can get into BIOS before the restart happens, I can select "deconcatinate" to dislable Optane - unless the key driver elements are already gone. https://support.lenovo.com/us/en/solutions/ht504146

Does anyone know of a "deconcatinate" tool that will schedule itself to run?

The warning text document - They need to show this FIRST! (That's unbelievable - they warned about data loss before that, but not about an unbootable system):

WARNING!!!!!!!!!!!!WARNING!!!!!!!!!!WARNING!!!!!!!WARNING!!!!

WARNING: Removing the driver files may result in the loss of 
data on any RAID volumes currently used by the system. Removing 
the Intel Rapid Storage Technology driver from the boot drive or 
bootable RAID volume will remove access to the drive and will 
require reinstallation of the operating system. To preserve data
integrity, backup all data before proceeding.

Proceed ONLY if you absolutely have all your required data
backed up from all single drives and RAID volumes present in the
system and ONLY if you have no need to access these drives or 
volumes after this operation is completed!!! If this is not the
case, please cancel and exit this Uninstall application.

Check your BIOS settings. There must be something called "Storage Controller" or with similar name with two options "AHCI" and "intel rapid storage technology".

Switch to AHCI and save settings and restart. It might solve your issue.

I solved this by using the Restore Point.

The advise I received here was way off. People need to take note. (Update - Most of the comments I was referring to have been deleted.)

I got a warning in the BIOS when I tried to change to AHCI, - if you continue all data on your hard drive will be deleted - so I said NO. I hard powered down to avoid a restart, and what would have been the blue screen of death. I put it a Windows 10 upgrade/install USB, and tried to do an upgrade to 1909. It told me I couldn't couldn't do a boot-up upgrade on the same computer, and I had to to the upgrade from within Windows (which meant rebooting - and failure). I hard-powered down again and rebooted with the Windows USB, and selected repair. Then I selected the Restore Point. It said it would reinstall the Optane drivers, but they might have a problem and should be reinstalled. The restore proceeded okay, and my system booted up okay.

I found a couple of posts about this model of laptop, and a few others, where AHCI can't be disabled, without a complete reinstall of the OS. There's a reason this computer isn't listed on Ubuntu's compatible computers list. I'm going to leave Ubuntu on the external SSD. (Update. Linux is working on the external SSD. Optane is enabled with the internal drive / Windows).

Here are three screencaps from the BIOS showing that the disk will be erased if I change to ACHI. (ACHI is the alternative to RST/Optane.)
