Red Hat Bugzilla – Bug 1027630
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
-i.e. MBR should begin with string "EFI PART"
Some BIOSes refuse EFI boot if the MBR is not compliant
Version-Release number of selected component (if applicable):
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
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.
