I'm trying to replace win 10 with Arch. Now only Windows 10 is installed.

I've created a bootable usb:

# dd bs=4M if=/path/to/archlinux.iso of=/dev/sdb status=progress && sync

Then I chose a temporary booting device to be my usb device with Arch and the end of the story: it showed me a black screen for a couple of seconds and then the menu "Choose temporary booting device" again. I've tried the same action a few times and each time it still showed me the black screen for a couple of seconds and returned back to the menu.

I haven't changed anything in uefi menu, maybe it's the reason? But what should I change? Or is the reason due to something else?

Note I want to remove Windows 10, not create a dual boot system.

    Go to your UEFI menu and disable "safe boot". If you bought this machine with windows 10 pre-installed it is likely locked to MS windows 10 by the safe boot feature. (Note that "safe boot" has nothing to do with actual safety.)

  • Depending on your UEFI menu, "safe boot" may be listed as "secure boot". In either case @grochmal is correct there is nothing secure or safe about that feature.

By default Windows 10 use a GPT partition table in UEFI mode. So, please use UEFI boot to install your Archlinux. If you setup is configured to SECURE BOOT, you have to disable and the bootable USB will start.

Maybe there are some other issues related to your bootable USB, because we need the USB drive are using a FAT format file (I already have this kind of issue) because in UEFI mode the /boot partition have to be in a FAT filesystem. The dd command just makes a bit-to-bit copy of the file, but doesnt format the USB drive. So, format the USB drive using a FAT format file and after that use dd command like you did before

dd bs=4M if=/path/to/archlinux.iso of=/dev/sdx status=progress oflag=sync

By doing this way, and disable your SECURE BOOT, everything will work fine.

    That last part of your answer is completely wrong. The dd command overwrites the USB stick with an image. The image contains a partition table and filesystems. So anything you have previously done to the USB stick - including formatting it - is overwritten and replaced. May 24, 2018 at 7:36
  • It's also way more efficient to use cat /path/to/archlinux.iso >/dev/sdx. The dd command should be your tool of last resort, not your first. May 24, 2018 at 7:41
  • I know that dd create the partition table from the iso, but I'm not sure about the filesystem. Anyway I will try again. May 24, 2018 at 13:34
