PARTED should check the GPT MBR validity
Last modified: 2014-10-07 19:47:05 EDT
Description of problem: Parted should offer LBA-0 validity check of the GUID partition table check as per http://en.wikipedia.org/wiki/GUID_Partition_Table -i.e. MBR should begin with string "EFI PART" Reason: Some BIOSes refuse EFI boot if the MBR is not compliant Version-Release number of selected component (if applicable): all How reproducible: easily Steps to Reproduce: 1. Take Win-8 EFI booting PC 2. Install Fedora 19 in legacy mode - LBA-0 gets destroyed as the installer overwrites MBR 3. Win-8 can not boot any longer Expected results: If we run parted from a recovery CD, we should be able to fix MBR
There are too many ways for things to be damaged. parted isn't a repair tool and really can't be expected to cover these kinds of cases. Whatever broke the MBR should stop doing that.
