After a couple of days of googling about it I still have some doubts and I would be quite grateful if anybody
could help me to solve them.
I have a Thinkpad t420s with dual boot (win7 and F15) that I want to upgrade to F16.
Usually when I upgrade I select to custom partition my disk, I keep the ntfs, /usr/local and /home partitions,
and reformat the rest. Then I restore my settings. Since my Thinkpad can use both UEFI and BIOS legacy
I was wondering about the consequences of installing F16. So here you are my questions:
1) The partition schema of my disk is MBR. Did I correctly understood that if I want to use UEFI I have to
pass to GPT?
2) Did I correctly understood that the only way to transform my disk from MBR to GPT is to backup the
partitions I want to save, erase the whole disk, repartition/reformat it, and then restore the saved partitions?
3) Is this worth the effort? That is, what are the advantages of using UEFI over BIOS legacy? Notice that my
disk is a 160Gb SSD, so I do not need terabyte partitions and boot-time is already pretty fast (around 10
4) If I decide to stick with the MBR disk is there any particular action I should do when doing the custom partition?
5) If I decide to go with GPT / UEFI, same question as the above (I already saw that the instalation guide
states "If your 64-bit x86 system uses UEFI instead of BIOS, you will need to manually create a /boot
partition. This partition must have an ext3 file system. If you choose to partition automatically, your system
will not boot." anything else?
Thank you very much for your help. Since it is the laptop I work every day on, I prefer to play it safe and
avoid to solve my dubts just by trials and errors.
P.S. Slightly off-topic. I saw in my searches that Thinkpad T(4-5)20 have problems while booting linux with
UEFI. Any more suggestions/references about this specific point?
