Anybody Know UEFI??

6 posts in this topic

Hello all.

Recently i got a Dell XPS 13 from work, and noticed that it has the option for UEFI. Now being that i got my A+ back in 2001 and with the rapid change in technology i am still in the BIOS age for now. All of my home machines still use BIOS and since this ultrabook has UEFI what better opportunity than to learn now about it now. Can somebody guide me to a proper website or share their experience with it? I am looking to do a dual boot with Windows 8.1/Ubuntu x64. So far googling and youtube have only shown me very little how on to actually set this up properly. When i enabled UEFI it shows the Windows boot manager as the only boot option and that's it.

Debian and Ubuntu both use the grub-efi package to set up GRUB for an EFI environment. The install process for Ubuntu should be about the same as Debian's. This link will tell you what to do if the install doesn't work.

Oh and make sure you're using the GPT partition scheme and not MBR.

One of my friends had an XPS 13. I managed to get OSX, Linux and Windows to triple boot on it. With OSX, I had to enable legacy mode for the boot loader need for a Hackintosh.

 

However, with Linux Mint, I could boot through USB by just disabling secure boot. I think secure boot will just boot from known images, to avoid booting from USB that can load kernel mode malware from the USB firmware.

for secure boot you would need a distro/os which has their bootloader signed i think with ms at this point?.. but its also possible to just enable legacy mode if bios supports and disable secure boot and just boot whatever thru usb/sd. atleast is what i ended up doing since the partition table started to get messy with 8.1 like 4-5 partitions just for windows
