![]() Drag-n-drop an empty folder onto the MPI_FAT32 shortcutģ. Drag-n-drop the Win7/8 ISO onto the MPI_NTFS Desktop shortcutĢ. Clover needs a FAT32 partition in order to boot, so this is on the 3rd partition.ġ. This is useful if you have E2B on a Removable USB Flash drive because Windows Setup can only access the first partition on a Removable UFD and so the first partition must be NTFS. When Setup/ WinPE boots, it will be able to access the files on the NTFS partition of the hard disk.Ĭhange #2 allows you to easily make an NTFS partition image from any Windows Vista/7/8 ISO using large install.wim files, and boot to it via Clover in UEFI mode. Partition 1 = FAT32 - for clover+E2B files.Added new menu for NTFS+FAT32 dual partitions.First time you ran the CSM menu you would get a 'syslinux alternative boot' menu entry - now fixed by changing PBR.BIN file which contained the 'SYSLINUX' text string.To clean up the original EFI, just mount it and delete the files you don't want (./EFI/ubuntu/., and rename(?) the bkpboot圆4.efi to boot圆4.efi, assuming that's the windows bootmgfw.efi copy. but the default of putting into BOOT shim圆4.efi as boot圆4.efi without grub圆4.efi simply will not boot, as several recent questions about"missing grub圆4.efi indicate. I suppose multiple runs of grub-install will work or combinations of the switches, one with -removable to properly set up the BOOT, one with efi-directory etc. I used to agree with oldfred that grub-install was not the problem, but trying to get the above setup with grub-install indicates I have to file several new bugs. The shim/grub combination will boot with secure boot both enabled or disabled. They typically do not have a nvram entry, so may boot when attached to any UEFI computer. The EFI/BOOT files are the device boot loaders. | shim圆4.efi (Good to have shim/grub copies here in case the ones in BOOT |ubuntu/grub.cfg (grub圆4.efi looks here regardless of where it is run.) | bkpboot圆4.efi (The old copy of boot圆4.efi, probably the Microsoft bootmgfw.efi.) | grub圆4.efi (Must be in the same directory as shim圆4.efi) The EFI partition Ubuntu directories EFI/BOOT/boot圆4.efi (A copy of shim圆4.efi) ![]() See bugs 1396379, 1173457, and 1229488, and add yourself to the "does this affect me" list. Leaving it as is will work, but you the have grub spread across two disks, and both need to be present to boot grub from sda. You can remove grub from the first disk by removing its "ubuntu" EFI boot entry with efibootmgr (and then optionally delete the files in the sda EFI/ubuntu (and rename the bkpboot圆4.efi to boot圆4.efi). Select the disk from the EFI boot menu (some function key at power-up). The Ubuntu device should now boot (the initial setup used the right UUID for the Ubuntu root, so no changes needed). You wont need the Microsoft bootloaders, but copying them is a good backup. Just copy everything in the sda EFI partition to the (empty) Ubintu disk's EFI. In UEFI the bootloaders are just files on a FAT filesystem. You still need to do the housecleaning of duplicate/old ubuntu entry in UEFI. This is why using Boot-Repair's advanced mode which walks you thru a simple chroot to re-install grub is easier. Sudo efibootmgr -c -g -w -L "ubuntu" -l "\EFI\ubuntu\shim圆4.efi" -d /dev/sda -p 1 Efibootmgr defaults to sda1 or first drive & partition, you have to specify drive with -d and partition with -p parameters.If UEFI entry not correct you can add new entry. And then use efibootmgr to delete (-b & -B ) obsolete ubuntu boot entry with old GUID/partuuid. You check GUIDs (aka parttype) to know if that is correct. If you have just copied files from where Ubuntu default installed to the ESP you want to use, you need to edit fstab and use efibootmgr to create new entry to boot from correct ESP. Sudo grub-install -bootloader-id ubuntu /dev/sda1Ĭheck that fstab & UEFI have correct entries. You may have to reboot & ESP must exist or reboot will have issues. How can I reinstall GRUB to the EFI partition?Ĭhange mount of ESP in fstab first, as grub-install will use default unless specified. You then mount correct ESP.Ĭan I install in UEFI mode with the alternate installer? How do I install Ubuntu to a USB key? (without using Startup Disk Creator)Ĭhroot method from live installer.
