Most questions and answers I’ve seen so far (like this one) are addressing solely booting problems after removing one OS from systems with a single SSD/HDD, but multiple partitions.
In my case, each OS has its own dedicated SSD and I assume that, after disconnecting the first Win10 SSD, the second Ubuntu SSD (which has been installed afterwards) does not boot maybe because of missing MBR.
Is there an way to fix booting on Ubuntu SSD alone, without OS reinstall?
