Reboot the VM and as soon as the grub boot screen is visible press the tab key. Add to the and of the kernel boot line loglevel=7 and press enter.

Hopefully, that more information as to the exact step where the boot process halts.

It worked! but it didn't bypass the boot.

It was not supposed to bypass the boot just provide additional log information and where the boot process was stopping.

Just out of curiosity how much RAM do you have in your computer?

1024 MB for Base Memory
16 MB for Video Memory

Sorry I meant physical memory on the host.

It's Alright, my computer has 4GB of DDR3 Memory.

Hard to say if it is the Mountpoint-cache line that is causing but with the step after and usually the later is probably the better answer. On my system the steps after the Mountpoint-cache line appear to be WRMSR trying to write the spectre code to the CPU.

Not sure what is the next step.

Have you tried deleting and recreating the VM yet?

I will try.

Did not work, At least we tried.

Might want to download that iso again, or get the 09-01 current ISO and as others mentioned, verify the md5sum. Providing you've allowed sufficient resources for the existing guest, put the iso in the Controller IDE [optical drive], boot and if you get the ISO boot menu, continue to boot the live medium (first choice). From there you can overwrite anything that you may have already created for the guest (partition table and so on). Then proceed with installation per the Arch Installation Guide.
I just went thru this process last week with the 08-01 iso (US). Also had some problems getting started and didn't get a live medium boot screen until md5sum verified the iso.
Uncertain that md5sum or not was causing the initial problem not getting boot menu, but the clean one booted as expected.
Other note, the Display selection didn't make any difference on this installation aside from the VBox caution message when VMSVGA isn't selected.

I don't know how to verify the md5sum...

Windows has a command line utility you can download:

https://support.microsoft.com/en-us/...ity-verifier-u

Compare that to the value on the Arch download page.

https://www.archlinux.org/download/

The mirrors should also have a text file with sums for each release.

Ok, I have install the windows 10 verifier. What do i do next?

If this a Linux host, navigate to the folder where the iso is, and providing you also downloaded the sig file run this command:
for the 2020.08.01 iso that is, if 2020.09.01 then change the command accordingly. If host is Windows I can't help, but looks like others here are able to help.

Just want to quickly say i have a file mirror for the iso i downloaded.
