I installed ubuntu a long time ago along side with windows 10, on an 240gb ssd, I have another 1TB HDD that I split into 2 partitions. One for ubuntu and one for windows.
Today I wanted to delete windows permanently so I formatted the partition that has windows on it .
I restarted the laptop but then noticed the it's still there on the dual boot menu .
So I formatted the 1TB incase there are some boot files there , but nothing changed.
I formatted all the partitions and reinstalled Ubuntu, and I still have the same problem.
Any suggestions or solutions?
