I just changed the battery on my Macbook pro 13" and now when I start it up I just get a Os X Utilities page asking me to either restore from Backup, reinstall Os X or use disk utility. The hard drive seems still to be working since I verified it with disk utility, bit it won’t start up on it. What shall i do? Thanks for any tip!
Well, do what it asks, run Disk Utilities and see if there’s a problem.
I could no longer boot to my newly installed Samsung SSD (replacing the original HDD) after changing the battery. But the SSD would boot when connected externally via USB. I discovered that the cable from the disk drive to the motherboard had been dislodged at the motherboard.
Once this was re-seated and tight, the SSD showed up again!
