win7 no longer appears on grub menu, also error while generating grub config
by andrewysk from LinuxQuestions.org on (#5C9HF)
I am using arch based linux, xfce. using legacy mode, MBR hdd.
This is my hdd partition:
sda1 windows7 reserve
sda2 win7 ntfs
sda3 / ext4
sda4 extended
sda6 logical ext4 /home
sda5 /swap
I have win7 install, and i also have eos linux installed
Issue1:
------------
Previously when i execute Code:grub-mkconfig -o /boot/grub/grub.cfg it always creates 2 lines for windows7:
1. windows7 sda1
2. windows7 sda2
While windows7 sda2 should not be listed.. I think it is generated when grub-mkconfig is because something have being created in sda2, which grub thought it is also and os of itself.
Q1.
What does grub look in every partitions when grub-mkconfig (so that it know to create a menu for a os that it detected or don't create when it see a partition that has got no os in it )?
Why in this case it mistaken SDA2 as an os loader when it is not ?
Scenario2:
------
So, i entered found a webpage said Code:disable os-prober in /etc.. but i lost the article now.. can't remember where was the /etc file that i have modified. I did however made bak copy of the file beside it before i made the change.
This "os-prober disable" fix the dual line win7 in grub menu. (i think i also went to grub config to mask out the "win7 sda2 boot menu".
*which now i come to think of it, it is not the right thing to do, because everytime when a kernel update or installed, it will be over written.
Today, i used the Kernel manager of EOS to install several kernels, lts , zen , hardened.. (just to have more kernel to try out). the Kernel manager did the grub config generating in background by itself.
Issue2:
--------
Booted the computer, it shows the whole list of kernels, but the original rolling release kernel is not in the grub menu.
Also Win7 is not in the grub menu.
I suspect it was due to the "os-prober disable" line that i have added in (i can't remember where is the file i added the line)
Q2.
What skeleton files that refers to byCode: grub-mkconfig -oI believe it looks for Code:/etc/default/grub as "template" to create grub config file.
I want to undo my previous *mistake* so, grub will able to show win7 and rolling release kernel.
Or is there way to grab and replace those files in /etc/default from liveusb ?
Thx
