after a lot of googling and failing I am now seeking help from you professionals!
Short summery:
I used to have a working dual boot with Linux and Win10 using a Radeon R9 Nano. After returning from a longer travel, I decided to get rid of my R9 Nano, which the system was running with. Removing that from the system did work well for Win10 so far. In order to have a cleaner cable management, after removing the GPU, I unplugged my SSDs (1 for Linux, 1 for Windows) and propably shitched their connectors. For a while now I was only using windows (due to autoboot that SSD), which did not give me any trouble so far.
But trying to boot that Linux SSD now, throws me at a blinking cursor with no possibility to see grub or boot linux whatsoever. When I press any key while that blinking cursor the next boot device is booted (let it be a USB-Stick or Win10).
So in conclusion, I can boot a Livestick and Win10 but not my Linux installation nor Grub itself. Besides I did not uninstall the AMD driver in linux, I assume the main problem might be a false Grub installation, since that drives may have swapped (sda/sdb/sdc ... - I have a HDD installed for data storage as well). So all my linux partitions lay on that one SSD (seperate /home and /swap).
Do you guys have a some hints or tipps, how I can repair grub or whatever again, to use my linux installation again?? That would be absolutely fantastic!
Thank you so far for reading my problem. Hope to hear from you.
