Hello,

I discovered that Gparted writes to the MBR (0 to 446 sectors) when it i= s empty.

Yesterday i used a live cd of ubuntu to delete a partition o= f my disk with Gparted. And my pc didn't boot after that.

My os is a Fedora server instal= led in UEFI. Note that Grub is not installed in the MBR or in the partition= . I don't know how but it boots fine like that.


So= i had to delete the code Gparted writed in the MBR (0 to 446 sectors) to b= oot again ("sudo dd if=3D/dev/zero of=3D/dev/sda bs=3D446 count=3D1&qu= ot;).

I think Gparted should not touch the MBR (0 to 446 sectors)= when it is not ask by the user.


Thanks

Thomas

While it is possible to use a msdos disklabel with UEFI, it should be using GPT. I'm also not sure why a UEFI system wouldn't boot with the MBR written. It should just ignore it and use the ESP partition. Brian -- Brian C.

While it is possible to use a msdos disklabel with UEFI, it should be using GPT. I'm also not sure why a UEFI system wouldn't boot with the MBR written. It should just ignore it and use the ESP partition. Brian -- Brian C.

Hello,

I discovered that Gparted writes to the MBR (0 to 446 sectors) when it i= s empty.

Yesterday i used a live cd of ubuntu to delete a partition o= f my disk with Gparted. And my pc didn't boot after that.

My os is a Fedora server instal= led in UEFI. Note that Grub is not installed in the MBR or in the partition= . I don't know how but it boots fine like that.


So= i had to delete the code Gparted writed in the MBR (0 to 446 sectors) to b= oot again ("sudo dd if=3D/dev/zero of=3D/dev/sda bs=3D446 count=3D1&qu= ot;).

I think Gparted should not touch the MBR (0 to 446 sectors)= when it is not ask by the user.


Thanks

Thomas
