I want to install Arch Linux in UEFI mode, but I fail at booting the installation media in UEFI mode. What I have done so far is:
- Create msdos partition table on usb key OR create gpt partition table on usb key
- write the official iso to the usb key with
dd bs=4M if=archlinux.iso of=/dev/sdX - reboot the system
When I try to select the dialog only shows me a BIOS/CSM entry to boot, which works perfectly. But there is option to boot in UEFI mode.
Aditionaly, when I try to view the partitions in gparted i get the message dev/sdd contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? and when I click yes I get the message The backup GPT table is corrupt, but the primary appears OK, so that will be used.
Also there is only partition that is unallocted and has a warning sign, when I view the details I see the errors listed above.
What have I done wrong? Have I forgotten something?
