Tips for troubleshooting boo tup

So I have a fresh installation of the November Arch Linux. The install was done via a USB stick on a HP Pavillion dm4. I re-sized the parent partition which has W7 using the windows tool. I then formatted the partition using the steps listed in the beginners guide. The install seemed fine. Upon booting the new installation on its own it typically hangs at this line:

/dev/sda4: clean, 31593/6406144 files, 648979/25600000

Sometimes if I boot using the fallback option I will get a few more lines commenting that it cannot write the logs, "filesystem read only" "chmod failed"

I tried checking the btmp and wtmp log files and they are empty. There is no boot log file. I presume this is because my system is read only.

My system:

HP Pavillion dm4
Dual booting W7 and Arch. Arch on sda4 partition.
Grub2, auto generated .cfg with a nomodeset option due to the Intel chip-set described in the beginner's guide, otherwise it boots a blank screen
VT turned on in BIOS, otherwise it says KVM is disabled by BIOS


W7 still boots fine. My opinion is the read-only issue is the thing to investigate. What other things should I look into to try and solve this? I am still trying to figure out the easiest way to get the necessary files to post here as well. Any tips are appreciated.

Re: Tips for troubleshooting boo tup

Looking into this issue further it appears that the root directory should be read only during fsck. So the next step is to check my grub install and configuration.

I know that when I installed grub i did not use the --target= option.

Re: Tips for troubleshooting boo tup

The ro kernel parameter is a legacy thing, and is no longer required.  In fact, it is actually faster to mount it rw or leave it out entirely.  This is because the initramfs actually fscks the filesystem while not even mounted, so if you specify ro, it then mounts the filesystem ro after fsck and then has to remount it rw (though this takes a split second really).

Why don't you boot from the install disc and then fsck the partitions from there to make sure they pass.  That can be one of the most basic reasons why a partition will not be able to mount rw.  In any case, the installer disc is basically a tool that you will probably continually come back to if you eventually succeed in installing arch.

Re: Tips for troubleshooting boo tup

So I followed your advice and checked the disks. I fsck the partitions and they were fine.

With the help of a friend, we booted the live disk and connected to the box via ssh. We then mounted the installed system:

mount /dev/sda4 /mnt

After which we used:

systemd nspawn -b -d /mnt

to boot the system. It booted just fine which suggested the issue lies within grub. Checking the grub.cfg file my friend recommended specifically identifying the path to my system rather than using grub's auto-generated config file method which searches for it. <---- I do not completely understand the command issued by grubs generated .cfg file

I edited grub.cfg. Upon booting I lost the GUI for grub. I manually entered the commands from my grub.cfg file and successfully booted the system. I will try to post the comparison of the two different grub.cfg files later. I now am trying to understand why the auto-generated script did not work versus a simple manual change.

EDIT: Here are the files. .auto is the original that did not boot, .cfg boots, but manually only (no GUI). diff output is the difference between the two. Also please excuse my immaturity for renaming the menu entries if you actually read this. I am curious why the auto generated one fails. I am going to look them over line by line myself and see what I can learn.

Re: Tips for troubleshooting boo tup
