I have a dual boot HP laptop (ProBook 450 G6) with an NVME drive and a SATA SSD.
NVME: Boot partition (including GRUB), Windows 10
SSD: Zorin OS 16 Pro, NTFS Data Partition
Unfortunately, the NVME has got some serious "health issues" and had been failing while booting into Windows. I made some tests with hardware analysis tools like hwinfo and CrystalDiskInfo and they both showed way too high temperatures (~82°C) and a health status of "99% bad".
I thought I could just replace the NVME drive. It turns out that I stupidly installed GRUB on this one though. So after taking out the NVME, I can't boot into Zorin anymore.
Also, I couldn't make a backup ISO from the NVME drive, because of error messages leading to do chdsk (which didn't help either).
Now my question is:
Could I reinstall GRUB on the other SSD where Zorin is installed (is this even possible?) and then take care of the NVME drive and install Windows back on it or should I try to do it the other way around?
Any help or experience or future proof "How-to-not-screw-it-up-again"-tips are welcome
