GPT vs MBR for SSD OS Disk ? (win7 install)

If I have UEFI BIOS, I'm going to use GPT. Only reason why I wouldn't is because the drive is shared between new and old computers (MBR has broader compatibility support). I wrote a guide how to install Windows on GPT here:
Installing Windows Vista/7 on a GUID Partition Table

No. Either you install on GPT via EFI boot or you intall MBR via BIOS boot. You can't install Windows and change it later.


Not only does GPT support booting to partitions larger than 2 TB, it also means the computer is booted using EFI which means it has a lot more memory to work with during startup. It should theoretically mean startup is quicker on EFI/GPT than BIOS/MBR.

 

GPT vs MBR for SSD OS Disk ? (win7 install)

So I cannot use all the new bios UI and fancy pre-boot evironiment if i don't use UEFI-boot ? With or without GPT?


I just want to use the UEFI without GPT: so can I UEFI-boot and install win7 with MBR?

Now I actually asked the correct question I wanted. Sorry it took time to figure out.

 

Converting MBR to GPT for EFI boot?

What you say is true enough. However, creating the EFI partition is covered in his step number 3.
