Very slow boot time

Postby fw190 » Thu Sep 21, 2017 2:38 am

Hello!

I had two partitions on my drive and deleted one which had the boot partition and was encrypted. This led to a grub only but I have finally managed to fix it and now I can boot to the main partition and system and everything works ok. The only problem is that it takes very long to start the system. I think that it is somehow connected with me messing it up in the first place...

I have commented out the swap as it looked like the one form the old system - commenting it out didn't help.

What can I do to bring the system back to normal boot time?

Check dmesg for errors and if you find any, post them. Just the errors, please, not the entire dmesg output.
If your problem is fixed, please mark your thread as [SOLVED] by editing the title of the first message in the thread.

Is it OK or is there any other way to search for errors? I have googled that method with grep and just instead of some random string a have written "error"
