Hello. I downloaded the most recent arch linux dual-boot install iso (from 2015-04-01). - checked it with md5 and sha1 against checksums from the website. Also did gpg verify. All okay. - burned to cd using Brasero. Verified cd from within Brasero. Okay. - verified by loop mounting, per website. Okay. Then booted cd. Got to initial menu, chose 64-bit install (computer is 64-bit). Then it stalls out, with error messages (can't copy because can't complete boot process). Sort of like: :: Triggering uevents . . . ... blk_update request: I/O error, dev sr0, sector 1226572 ... blk_update request: I/O error, dev sr0, sector 1226572 ... Buffer I/O error on dev sr0, logical block 153344, async page read :: Mounting '/dev/disk/by-label/ARCH_201504' ^@ERROR: device did not show up after 30 seconds . . . I burned another cd, and got the same exact results, including the same exact error messages. I have had no other problems making and using other cds or dvds, including images of other distributions < ducks : ) > Note: I can (and have) installed ARCH on the same computer, using the Evo/lution 0.4 installer - works fine. But I want to learn to install The Arch Way. So, is the Arch iso from 2015-04-01 defective as published? Or, what else might be wrong?
