I have an UEFI Bios and a working bootable system. My boot time is about 45 seconds which seeems slow to me as I use an SSD for my OS. Is there a way of speeding up boot time?
EFI can be faster, but that's not certain. The biggest speed
difference is in hardware initialization early in the process. On my
systems, this is a fraction of the total boot time, so a reduction in
the hardware initialization time, while good, doesn't make all that
So, i have this rather strange problem:While most people encounter issues when they want to boot with UEFI, i can boot UEFI just fine, but am having issues when trying to boot having the Compatibility Support Module (CSM) of my W530 enabled. CSM still boots my Arch via UEFI, but emulates some features of a BIOS system (like running/loading the VGA BIOS).
This isn't totally true. It would certianly be easier to get UEFI working by initially booting ito some Linux UEFI environment. But you could also just put the boot manager or bootloader at \EFI\boot\bootx64.efi and configure it. Then set the system to boot UEFI and choose the drive that has this ESP, and it will take you into that bootloader. So assuming it is then co
All boot disks seem to be traditionally legacy. UEFI is fairly recent. Setting my laptop to legacy boot only, will boot Parted Magic from USB key but not my OS. Setting dual boot order to legacy first then UEFI, does not have the desired effect. A happy medium is to hit F12 then choose boot device from list.

My revised boot order remained the same in the BIOS, but UEFI always took over even after changing the comp to legacy boot and disabling secure boot.I was able to boot from USB by pressing ESC to access
I'm struggling to boot Ubuntu from bootable USB I've made using unetbootin. In the older days, when booting laptop you could go into bios and set the boot device. Now I can't set one. There's no hotkey I could press during boot to open up BIOS.
Yes I am still using the old 17. I have a liveiso of 20 but can't quite figure out how to install it. Well I'll just upgrade one version at a time.
Anyway here's my question. I have tried everything and I don't know how to make my usb bootable from BIOS. It's not the BIOS that's the problem. I'm using grub-mkimage, syslinux and something called rufus. I want to boot isos.
I had installed Ubuntu and Windows(an ext4 partition and an NTFS partition for each) in the LEGACY boot mode,not knowing what difference it would make if I installed in UEFI instead.But I have been encountering problems related to slow boot,especially while waking up from suspend/sleep.I searched in the internet and found out that UEFI is newer than Legacy and has faster boot/waking up time.
