I tried to restart while keep pressing Command-R
However, my keyboard is not mac keyboard. There is windows-R. It works exactly like Command-R in all circumstances.
Well, I keep failing to get into recovery HD. I need that because I want to repair the main disk.
Error: This disk needs to be repaired using the Recovery HD. Restart your computer, holding down the Command key and the R key until you see the Apple logo. When the OS X Utilities window appears, choose Disk Utility.
What should I do?
I have a flash disk. Can I turn that into recovery HD?
