I'm working with a 2012 Mac Book Pro running Yosemite. There is clearly some problem with the disk but holding Command R on reboot doesn't launch disk utility. It just launches directly into internet recovery which is perpetually stuck at 5 %. I bought the computer in the US but am currently opperating from China. Would that make any difference? Please help!
MacBook Pro, OS X Yosemite (10.10.2)
Try booting using startup manager:

Then select the recovery partition.
Any difference?
Ciao.
When I use the recovery disk, it goes to a grey screen for about a minute and then just shuts off.
May I assume that the MBP will not boot or operate which is prompting to access the disk via recovery? If you could provide some more details, that may be helpful.
Ciao.
There are a number of small glitches during operation (like the screen suddenly going dark and then coming back) and performance is really slow so I backed up my files and wanted to just wipe the drive and start over.
Having backup your data is very prudent. Based on what you have tried, try booting the MBP OPTION + COMMAND + R keys. This should result in a display with a revolving globe. By following the directions, it will allow you to connect to the Apple servers and install the original OSX that came with your MBP.
If that fails, then you will have to connect a boot drive to your MBP in one form or another (a boot in a HDD enclosure or another Mac via Target disk mode) and access the internal HDD via Disk utility>First Aid. The internal HDD should be repaired or replaced.
Ciao.
