How to fix mbr in linux or gparted, etc. (for a mbr partitioned disk)
I am used to using gpt disks, therefore I was using gptsync to fix mbr.
I do not know if gptsync can fix mbr in mbr disks, which I think not. I am wondering if there is any command that I can use like gptsync to fix mbr of mbr disks. Code:
sudo gptsync /dev/sdX But I don't know what can solve my problems in mbr disks. And gptsync works if there is any grub or not in the drive. That is the kind of solution I am looking for, even if there is no grub, can mbr be updated? In gpt disks, whenever I have a problem, I can easily delete the first 200 MB Protective Partition and run gptsync, and everything would be fine. Is there any solution like this for MBR disks? Thanks. |
there is grub-install. if you got a backup of the partition table this mite work:
Code:
dd if=mbr.bak of=/dev/sdb bs=512 count=1 |
Surely this can't be a common problem. What the heck are you doing that you need to recreate the mbr that often?
Anyway, the disk label can be written with parted. If you need a boot loader as well, then use grub-install. gptsync creates a disk label (mbr partition table) from a gpt. If you don't have a gpt, and your mbr is corrupted, parted can find your partitions with "rescue" mode. |
