Download iso image live-efi-boot-disk-amd64-171028.iso, boot a live session from it, then on the desktop double click the rEFInd installation icon.

Run the installation twice so that it reads "rEFInd Boot Manager set in Fallback mode..."

First installation rEFInd will be setup in Prioritity mode. Re-running installation will change rEFInd setup to Fallback mode. In this mode any EFI computer, even computers with buggy EFI firmware will load rEFInd Boot Manager at startup.


I tried to install this but it says: Cannot proceed. You need to boot the Live USB/DVD in EFI mode


I'm past that issue, now it says Ubuntu EFI folder not found Debian EFI folder not found Can't proceed

LM installation was likely Legacy.

From the Live EFI Boot Disk live session check your are connected to internet then double click the bisnext online summary launcher on the desktop. That will detail current installation setup.

See first line of summary, only provide the URL link, don't copy paste entire summary it's too large.

Your bisnext online summary was uploaded here http://paste.debian.net/994358

Summary confirms LM was installed in Legacy mode.

As Windows was installed in EFI mode, you need to install LM in the same mode Windows was installed, hence in EFI mode.

Boot LM installation media in EFI mode and reinstall LM.

Before installing check the boot mode using the following command:

Code: Select all

[ -d /sys/firmware/efi ] && echo "EFI mode active" || echo "Legacy mode active"

Only proceed with installation if command output confirms EFI mode active.

When done with installation reboot normally, if grub doesn't automatically load at startup then install rEFInd Boot Manager in Fallback mode as already explained.

Notice your disk current partitionning is inconsistent, sda8 partition type Microsoft basic data was formatted as an ext2 Linux filesystem, sda13 125 GB size type swap, sda9 1 MB size type swap.

HP BIOSes have a well known issue with alternative EFI bootloaders (other than windows). Here are some fixes to try:

1. Try updating youtr BIOS. HP fixed this pretty much in 2017 with new BIOS releases for their Elitebook/Probook lines

2. Revert to legacy/MBR booting, if you don't want to keep windows 10.

3. Try refind as stated above.

4. Read all this:

Go to the "unstable state"

My apologies. The problem with the install is the very abnormal 2nd swap partition with an over-large size of 125.9GB, ie not with the swap dev file system. Normally, an installed Linux system has only ONE swap partition that is about 2X RAM size or same size as RAM.
... So, you likely need to reinstall LM by using the manual "Something else" install method, deleting all the Linux partitions to create a new free space for a repartition and reinstall.

For some guidance on dual-booting LM alongside Win 10/8.1 in UEFI and GPT-disk mode, please refer to .......
viewtopic.php?f=42&t=163126 (dual-booting UEFI computers)
https://sites.google.com/site/easylinux ... ct/windows
https://sites.google.com/site/easylinux ... nt-install
https://www.tecmint.com/install-linux-m ... uefi-mode/ (note step 18)
viewtopic.php?f=42&t=122276 (manual partitioning Tutorial)

Ensure that Secure Boot, Fast Boot and CSM are disabled in BIOS setup, Fast Startup is disabled in Win 10/8.1(>Control Panel >Power options), the Live LM media(DVD or USB-stick) is booted in UEFI mode in BIOS setup.

To dual-boot, you only need to pre-shrink the Windows partition if you intend to use the manual "Something else" install method. The automatic "install LM alongside Windows Boot Manager" method will be followed by the LM Installer auto-partitioning the disk and auto-installing the Linux Grub bootloader onto the Windows ESP. Only a root / and swap partition will be auto-created with a total default size of about 20GB. The user will be given the option to increase this default size by moving a slider on the colored Partition table, subject to the maximum available free space in the Windows partition.

For the "Something else" install method, ensure that the "Device for boot loader installation" is the Windows EFI System Partition(= ESP = fat32/about 104MB) which is usually dev/sda1.
