You may need apt install syslinux if you don't have syslinux installed already. That way your grub will find the config prepared by the System Rescue developers, too. This will install your OS version of grub to the USB flash drive in EFI mode.Ĭopy boot/grub/grubsrcd.cfg from the extracted ISO (or the Flash drive, it is there already) to /mnt/RESCUE701/boot/grub/grub.cfg renaming the file. Grub-install -target=x86_64-efi -recheck -removable -efi-directory=/mnt/RESCUE701/ -boot-directory=/mnt/RESCUE701/boot/ to /mnt/RESCUE701.Ĭopy the boot, EFI and sysresccd directories from the (extracted) ISO over to the root of your flash drive partition. Mount the partition created in step 3 above, e.g. If you are upgrading a flash disk from a previous System Rescue version, fatlabel /dev/sdX1 RESCUExyz will do. This label is used to find the root file system. It is crucially important that the label of the partition is "RESCUExyz" with x.yz being the version number of System Rescue you are putting on the flash drive. I do not have any systems that need an EFI partition so I skip GPT and EFI partitions. Use gparted, parted, cfdisk or sfdisk to make MBR partition table and a single primary partition of type "FAT32 LBA" (type c). But if you read this a few months down the line, it will be a newer ISO. I am using System Rescue 7.01 which is the last release as of now. Download System Rescue and unpack the ISOĭownload from and extract the files from the ISO.Ĭd MYTEMPSPACE & 7z x ~/Downloads/ or so will do. I did this on Debian Buster but with some adjustments to paths and what packages to install, any recent Linux distribution should do:ġ. The basic idea is to use the bulk of the System Rescue ISO contents but amend these with your own grub and syslinux so they work as intended over the supplied ones that are bound to the ISO layout a bit too much. I much prefer to have a flash drive that I can write to over an image of a CD (ISO) written 1:1 onto the flash media. They recommend a dd or the fancy graphical version of that, called usbimager. The "Installing on a USB memory stick" documentation is good for Windows (use Rufus, it's nice) but rather useless for Linux. With this their ISO layout changed substantially so when updating my trusty recue USB flash drive, I could not just update the kernel, initrd and the root filesystem image as I had typically done every other year before. Maybe it is faster to simply install Windows 8 again on a UEFI PC.System Rescue, the project formerly known as System Rescue CD, has moved from being based on Gentoo to being built on Arch Linux packages. The procedure to convert BIOS to UEFI is rather complicated. Note that you can’t use this method to convert a BIOS installation to UEFI because the EFI partition would be missing in your backup. Initialize disk with GPT partition scheme Windows 8 booted up in UEFI mode without problems afterward. The solution was to boot from True Image boot media and then initialize the disk with GPT (Tools -> Add new disk -> Initialization Options.) I could then selectively restore the partitions from my backup. I wasn’t even able to delete the partitions on the SSD with the Windows 8 disk management tool on my Windows To Go installation. I guess the reason was because True Image tried to copy its Linux-based OS to the SSD, which was somehow totally blocked. Restore a GPT partition scheme with True Image True Image then tried to boot up its own operating system, but this failed with the error message: Kernel panic - not syncing: VFS: unable to mount root fs on unknown-block(1,0). However, it appears True Image was no longer able to modify the SSD disk, even though I booted up from a USB stick. In disk mode, True Image automatically detects that the backup was created from a GPT partition scheme. Unfortunately, it wasn’t so easy to get rid of the BIOS installation again because a restore in disk mode failed. This was enough to convert my Windows 8 installation from UEFI to BIOS. What happened? Since I restored in partition mode, Acronis True Image initialized the new SSD with the MBR partitioning scheme and not with GPT. I wasn’t very pleased because I knew that the PC wouldn’t boot up if I changed the configuration back to UEFI. Restore a UEFI installation as BIOS installation with True Image
