Hello, this is the timeline of what i did and what problems i had:
Initial state: Corsair MP510 960GB NVME SSD with Manjaro Linux installed on it
Booted from an USB drive with manjaro live cd on it, used GParted to delete all the partitions on the SSD and create a single NTFS partition.
Booted from an USB drive with Windows 10 1909 installer and proceeded to install windows on the SSD normally
Computer rebooted automatically after the installer finished (booting to the SSD), throwing an error about not recognizing the partition's format and entering GRUB Recovery mode.
I booted into the manjaro live cd usb drive again to do a sanity check and confirm that all linux partitions were deleted.
I also tried the windows installer again, using the format option in there this time. error persisted.
I used the USB drive with the windows installer to enter troubleshooting mode and use diskpart on CMD. the following commands were entered:
LIST DISKS
SELECT DISK 3 (the ssd)
CLEAR
CREATE PARTITION PRIMARY
FORMAT FS=NTFS
ACTIVE
Then i proceeded install windows on the SSD drive again. The installation went normally again, but this time after the automatic reboot the computer threw the following error:
"An operating system wasn't found. Try disconnecting any drives that don't contain an operating system. Press Ctrl+Alt+Del to restart".
I double checked and yes, the computer was trying to boot from the NVME SSD.
And this is where i sit, i don't know what the heck is going on here... any help is appreciated.
Thanks for your attention.
