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?
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.
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'm having a problem with my Kubuntu. It's almost a fresh install (I've only installed the typical apps/codecs only).
Sometimes it boots fast, and sometimes it boots slow. It's almost random. So, I installed bootchart and now I bring you the logs of a fast boot and a slow boot. I don't know why dmseg says the boot time is almost the same (~52 seconds).
Well with a new uefi motherboard comes new nvram, so did you create a new uefi boot manager entry with efibootmgr? Otherwise you could copy your desired bootloader to \EFI\BOOT\BOOTX64.EFIedit: the path above is what the standard indicates is the default uefi application. So it is used when you use external media to boot from for example, in which case you would not have a boot manager entry.
I removed Windows Boot Manager option from BIOS (UEFI) with EasyUEFI, after reboot I got an error message about broken BCD, I tried to reinstall Windows 8.1.1 Pro X64 from USB installation, which I prepared with Rufus, there I set GPT partition scheme for UEFI computer, but when I tried to boot from this USB and perform installation I get the message Operation System not found.
