Can someone help me figure out my grub.cfg, thank you in advance :]

[bonkers]

Acording to this site http://askubuntu.com/questions/43732...-edit-grub-cfg , I should be able to

Edit /etc/grub.d/10_linux instead and run sudo update-grub when you are done. This is a more reliable method, otherwise every time you upgrade to a new kernel your /boot/grub/grub.cfg will be overwritten and you will lose your changes.

but when I attempt to edit /etc/grub.d/10_linux , no such file exists. So I have posted my /boot/grub/grub.cfg and I would hope someone could take a look at it and see if anything is wrong with it. I am using Kubuntu 14.04_64 / single boot / with kernel 3.17.2-031702-generic #201410301416 SMP. I had to resort to using Grub Customizer to configure my grub, however I had a few questions. Why is MSDOS included in the set root='hd0,msdos1' part of the .cfg file. Why do I have a /etc/grub.d/10_linux_proxy, is this normal? I have compared my grub.cfg to fresh post install .cfg grub configs and it looks different.

I also noticed ( and I apologize for adding this in here ) this is part of my fstab

UUID=c2590e88-813b-4481-b1e2-cfc449cedb00 /               ext4    noatime,nodiratime,commit=600,errors=remount-ro 0       1
# /home was on /dev/sda2 during installation
UUID=ac1aefd2-69aa-4ce2-9341-3f28a1c816b9 /home           ext4    defaults,noatime       0       2
# swap was on /dev/sda5 during installation
UUID=f7c78b56-7e43-40b7-8764-f1b69c256066 none            swap    sw              0       0

Should each partition have a different UUID or is that for the entire disk? In my dmesg (SDA1) / partition shows up as this

EXT4-fs (sda1): re-mounted. Opts: commit=600,errors=remount-ro

I am wondering why the noatime nor nodiratime is shown up, not to mention that this SSD is stuck in UDMA5 mode and it is a 256gb SSD Crucial M4 2.5 Model Number: M4-CT256M4SSD2 with firmware 070H which ran just fine under Windows, no I am NOT bashing Kubuntu, but I wish to somehow get some answers. Thank you for your time, whoever responds to this, really I appreciate it.

What is it you're trying to accomplish?

Edits to 10_linux might get wiped out also if grub gets updated so why edit it either? There's really no reason to muck about with grub.cfg at all as it gets wiped every time you run update-grub (like when a kernel is installed). I suspect you have 10_linux_proxy because you installed and used grub customizer - but that's just a guess. The "msdos" reference is to the partition table entry and has no other effects - so again - why mess with it? Is something not working right?

If you want to change something in grub you should edit /etc/default/grub (and then run update-grub) or use System Settings > Start Up and Shut Down > GRUB2 Bootloader. If you need to add custom entries to grub, you're supposed to edit /etc/grub.d/40_custom or 41_custom.

Also: Don't apologize for adding the part about your fstab and mounting questions - start another thread. You buried those questions in a thread about grub. You'll get a lot more help with those questions if you post a new thread with an appropriate title.

Edits to 10_linux might get wiped out also if grub gets updated so why edit it either?

Actually /etc/grub.d/10_linux is a so called "conffile" (of package grub-common), so it should not get automatically overwritten on upgrades (http://raphaelhertzog.com/2010/09/21...naged-by-dpkg/)

There's really no reason to muck about with grub.cfg at all as it gets wiped every time you run update-grub (like when a kernel is installed).

Yup, directly editing grub.cfg is futile (as is resistance).

I suspect you have 10_linux_proxy because you installed and used grub customizer - but that's just a guess.

Probably a good guess at that, although I haven't used grub-customizer and can't really confirm it.

What is it you're trying to accomplish?

Yes, tell us what you wish to accomplish and we'll be better equipped to provide directions.

[jlittle]

The file you're supposed to edit is /etc/grub.d/40_custom. Also, you can add your own scripts to that directory. If you don't want what's in 10_linux, you're supposed to chmod -x it.

If you really want to take control, though, and hack grub.cfg as is your wont, one way is to create a small partition and install just grub on it. This is good when you've got several linux installs that you keep updated; they don't trample on each other, You can keep one as the master install, but if you want then to reinstall that one, and the reinstall fails, you get the grub rescue prompt.
Of course, you have to update your grub.cfg manually, but ****, it's just a boot loader, so long as it does the job who cares how old and out of date it is. I update mine when there's a new install, and every few years have a look at where grub has got to and maybe redo my customizations on a recently generated grub.cfg. Last time I just ripped out all sorts of junk, my grub.cfg is about 100 lines, Trusty's one is 445.

[oshunluvr]

Kubicle: I assumed if grub-common got an upgrade, it might include 10_linux. I didn't think about the "keep the current version" pop-up. Thanks for the correction.

[bonkers]

Guys I just realized, I have

BEGIN /etc/grub.d/10_linux_proxy

NOT /etc/grub.d/10_linux, is this normal behavior.
