No, these commands are present at Arch Linux boot image by default. I don't know why it tells you that these commands are "not found", maybe there is a problem with your USB Arch Linux boot media - either on software or hardware level. Verify the checksums of your .iso file before writing it to USB, try another USB drive, etc. chattr executable file is probably located at /bin/chattr or /usr/bin/chattr , you could try running this executable file by writing its' full system path if you are afraid that your PATH variable became corruptedWhen I issue the CHATTR command is comes back with NOT FOUND. It's like the command is not available on the Linux Distro, neither does the LSATTR work ... Do I need to add those commands to the Arch Linux Boot image?
1.When i do command printf have issue: write effor : invalid argument
2. Nomodeset with space before or no?
Thank

1. operation not permitted / invalid argument - First of all, please check that you have successfully removed the previous variable with rm command. Write ls command and check if this previous variable has been removed. Then you could try again
Next time, please try to show a full photo of your screen. For example, I cannot see what is happening at the left edge of the screen, e.g. why "root@archiso" shifted 2 characters to the right. It could be that your EFI variables partition became unmounted because of some error, or that it became read-only somehow, and that is why you can't write a correct value to this variable using printf
Please try again from the beginning, hopefully it will work for you at the next time
These instructions already worked for many people - even if not at the first try
2. nomodeset - of course with a space before, and with all the lower case letters: nomodeset - OK , Nomodeset - FAIL
