After a little more persistence I have come up a step by step workable solution for migrating from BIOS-Legacy to EFI bboting so I'll answer my own question now. This applies only to booting multiple copies of unbuntu (or some flavour) and assumes you are starting from scratch with a new or repurposed drive and that your motherboard is fairly new (mine is ...

if anybody encountered the problem that the usb stick doesn't boot in UEFA mod you need to format the USB Stick in FAT32 instead of NTFS.It will boot then in UEFI even if Secure boot is enabled at least using rufus. For the second problem namely how to disable secure boot when it's grayed out i haven't configured yet a solution for that.

Microsoft offers a free Windows media creation tool that does that. If your secure boot setting is greyed out, this may be your best bet. From this Windows site, you can download a Windows 8.1 iso directly to a USB flash drive. That one works. I have used it. Click the Create Media button downloads mediacreationtool.exe. Use that to prepare the flash ...

Use universal iso creator and just create a bootable ISO. All laptops will accept this interface for boot and install. Here is a link to the product- http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/ The distro you need to select is windows 8.1 then select the iso then the drive you would like to use. I have personally down 1000s of ...

is it possible to share the contents of your /boot/grub/grub.cfg file (the one that loads the OSes) from the terminal (with networking eth or wifi) run: Blockquote cat boot/grub/grub.cfg |pastebin This will output a http://paste.linuxmint.com/..... url can you share that here so we can hopefully help fix or modify it to get BOTH systems back up and ...

First, try disabling Secure Boot. Although Ubuntu should work with Secure Boot enabled, there are occasional bits of flakiness that cause problems, so it's worth trying it with Secure Boot disabled. Second, I note the following from your Boot Repair output: efibootmgr -v Timeout: 2 seconds BootOrder: 0000,0001,0002 Boot0000* ubuntu ...

Once Windows is installed in EFI mode, booting it in BIOS mode requires significant reconfiguration, and vice-versa; however, doing a one-time boot from an external medium should not cause disruption to your Windows installation, no matter what the external medium's boot mode. Note that in this context, you can repeat a "one-time boot" as often as you like; ...

Windows 8 and 8.1 will work regardless of if you're running in Legacy or UEFI mode. If you're interested, you can check which BIOS mode your computer is running in by following these instructions. You can learn about the differences between UEFI and Legacy BIOS modes by going to this superuser thread. I think what you probably want to research, based on ...

I have tried doing it in another way. Try installing windows XP first in C drive, and then install windows 7 or 8.1 in D drive. The boot menu will automatically do everything and you won't have to do any tweaking or extended settings. Hope this helps.

The main important part of UEFI is you should use GPT partition and 64bit OS. But remember do not convert External drive to GPT. The boot partition (usually 100 MB) must be in FAT32 Depend on motherboard, some motherboard read the GPT boot automatically without doing anything after you convert it from MBR.

If you want to boot windows through UEFI, you must boot windows installer through UEFI. I'm not sure about windows 8.x, but for windows 7 installation media you had to do some manual fiddling around - last paragraph on https://www.thomas-krenn.com/en/wiki/Creating_Windows_UEFI_Boot-Stick_in_Windows This was probably why you couln't start the installation ...

It won’t work because you have a non-official ISO image. You need an unmodified Windows 7 x64 ISO image. Windows 7 x86 aka 32-bit is not UEFI-compatible.

If you want to change your win8 logo, Google 8oot. It works and you just need an image and it will do the rest! Works on every pc with win8 and win8.1

You can't do what you want with GRUB, but you can do it in at least two other ways, at least with most UEFI-based computers: You can use your firmware's built-in boot manager. Typically, you access this via a function key early in the boot process. It should present options to boot whatever EFI-mode boot programs you've installed (such as GRUB, probably ...

The latest version of Rufus allows seamless UEFI boot from an NTFS partition. If you select a Windows installation ISO, set the partition scheme to GPT partition scheme for UEFI computers and also set the file system to NTFS, Rufus will add everything required to allow booting NTFS partition from an UEFI system. Outside of using Windows installation media, ...

As far as I know, no. While you can use MBR-partitioned disks within UEFI, you cannot use BIOS (MBR) format bootloaders, as they expect to run in a mostly "fresh" system, not inside the UEFI-prepared environment. So GRUB.efi doesn't even attempt to start one; it expects you to give an .efi path only.

I don't know much about boot disks, but perhaps you did something wrong while creating the boot disk. If you have a computer running Windows, OSX, or Linux, you can use a boot disc creator. If you have a windows computer, I would recommend YUMI by pen drive Linux. It is a very esy to use tool, and is even multi-bootable. This means you can have more than one ...

I would install from a virtual CD ROM which you can get from here - or any other if you have a preference. It looks like the old 7zip trick to reveal the .exe does not work.
