What does "doesn't boot" mean? No error messages? Some frequent candidates are a drive configured in RAID mode which you'll want to switch to AHCI or adding the vmd module to your MODULES=(vmd) line in /etc/mkinitcpio.conf and rerunning mkinitcpio -P from a live disk. Other possibilities are a generally broken EFI implementation, from a live disk and a chroot into the system what are you outpus for
efibootmgr -uv cat /var/log/archinstall/install.log
efibootmgr -uv
EFI variables are not supported on this system
cat /var/log/archinstall/install.log

/dev/sr0 is your CD/DVD drive. Are you trying the live boot from an optical drive?
Have you checked the BIOS if the drive you're trying to boot with is the default?
I managed to boot into a live mint, the issue was with the bios that needed to be updated apparently.
This laptop by default isn't very linux friendly and needs a bios update to work with it.
I updated the bios and reinstalled arch, alas it still doesn't boot.
You booted into a live medium in order to do your initial installation - can't you use that same thing now?
Yeah I didn't think about it, my head defaulted to a live with a gui for comfort.
As for describing the symptoms, you say that arch linux appears in the boot menu, but what happens when you select it? We get that it doesn't boot - but what does this look like? Does it return to (or stay on) the same menu? Does the screen flash in any way? Does any text flash by? Do you see a blinking cursor? Etc, etc. Tell us what you see.
Nothing happens, screen goes black for a fraction of a second, then same screen.
Also, I found a guide to install ubuntu on this laptop, I know arch is not ubuntu but there's a few bios settings I'll try to follow and see how that goes, if it works I'll post what I did in case somebody else needs help and finds this thread, if it doesn't work I'll come here with an update and more info.
While I'm at it, I'll leave the link I found.

EDIT:
Well, no positive outcome. It's late here and I'll try again another moment.

/dev/sr0 is your CD/DVD drive. Are you trying the live boot from an optical drive?
Have you checked the BIOS if the drive you're trying to boot with is the default?
/init: line 49: can't open /dev/sr0: No medium found
