I have received a new Lenovo T420 laptop with Windows 7.
The disk now contains:
- a hidden SYSTEM_DRV boot partition (1.17 gb, 400mb used). I'm guessing this is the EFI partition, the laptop comes with UEFI instead of legacy BIOS. This partition is NTFS formatted.
- the win7 partition
- a rescue partition
As I've come to understand, the bios is EFI but MBR is used, not GPT.
Since I'm going to install linux anyway, I figured it would be a good idea to convert to GPT.
I found the tool fdrive, that offers the option to covert the MBR partition table to GPT partition table. But I don't know what happens with that boot partition, with the windows installation and things like that.
If anyone has looked into such issues please advise. Maybe there's something I dont understand.
