Are there any other way to restart to recovery HD 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?

Select Recovery HD and then click the upward-pointing arrow below it to boot from Recovery HD. 
After a brief delay, you’ll see the Mac OS X Utilities screen. Select Disk Utility to repair your disk:
