[SOLVED] Change BIOS from Legacy to UEFI boot ?

[EMOZE]

Dell Latitude e5550 is currently set to legacy boot; can i simply change it to uefi boot?

just now discovered it was set that to Legacy (bought it used off eBay re-seller over a yr ago with Win-10-pro & new Samsung 500GB MZ7LN512HCHP-000L1 ssd)

- is it OK to simply reconfigure bios from current legacy boot setting to uefi since it has the newer ssd in it? ?

or will it then fail to boot?

is there any reason to do it?

is not a new laptop, not under warranty. and no reason

If you don't need the laptop, meaning you have another system. then try it.

If your drive is MBR and need to convert to GPT in order to use in UEFI, you dont have to reinstall the entire disk

Checks if your drive is MBR format

Follow the link to convert MBR to GPT, you will need to use /allowFullOS to work.

You can specific the disk number if its not 0. Eg, mbr2gpt /validate /disk:0 /allowFullOS

Once completed, restart and boot immediately into bios page and change boot mode to UEFI and viola.
