New Initrd Needed: Howto Create A Speedy One?

Ubuntu 12.04

I installed updates, which included a new kernel. I went to remove one of the older kernels and got:

I have no idea how I'd "ensure there are no errors" in the /etc/grub related files... I have no idea what's supposed to be there. Looking at the line it's complaining about in /boot/grub/grub.cfg.new doesn't tell me anything. How do i find out what it's unhappy about?

On my Antix13 (similar Debian Wheezy), I have installed bootchart2 and pybootchartgui.
I have created entries in /boot/grub/menu.lst (see below),
but there are no /var/log/bootchart.tgz as per https://www.debian-administration.or...with_bootchart or http://forums.debian.net/viewtopic.php?f=16&t=38869
What should I do? I made perhaps something wrong.

Hi, I'm pretty new to Linux.

I'm currently working on a project in my Linux Administration class, but have run into a bit of a bump.

I'm tasked with booting Linux (currently using CentOS 7) through the GRUB prompt. I've loaded the kernel, but I'm having an issue with the initrd.

I've tried both of these commands:
"linux /boot/initrd-plymouth.img"
"linux /boot/initramfs-3.10.0-123.el7.x86_64.img"

Neither of these commands have worked. It only returns the message "invalid magic number" for both of the commands. Any ideas on how I can fix this?

Thanks for any help in advance. It should help me understand Linux better!

Hello,

I loaded the legacy OS 2 files from the ISO (vmlinuz, initrd.gz and pup_214.sfs) into a CF card (on an IDE adapter in my old PC). This CF card can be mounted on an USB adapter later for booting diverse PCs.

It boots..
and stop later with an error.
... looking for Puppy in .. (diverse devices) DONE
... looking for pup_save.2fs in .. (diverse devices) DONE
... (STOP TO PROMPT) cannot find Puppy in idehd.

Question: what is the reason of stop? should I perhaps use a specific boot code?

my syslinux.cfg has
label puppy
kernel vmlinuz
append initrd=initrd.gz PMEDIA=usbflash

Hello

I have installed a CentOS 6.4 on VmWare.

Now, after several days of using it, it suddenly does not boots. There is a problem with its initialization, here is the error:

Kernel Panic : Unalble to init. Try passing init= option to the kernel.
Pid 1 : Swapper not tainted.

I have used CentOS.iso to rescue it, but it still does not solve it.

My grub.conf contains:

I want to change the menu on a Suse 12 Enterprise system.
I edit the /etc/default zip12grub.conf file execure grug2-mkconfig. Then reboot the system and no changes occur. The zip12grub.conf seems like the correct file to update so I am at a loss as to what the correct process would be.

cat zipl2grub.conf

When working with a virtual terminal, I find it often easier to edit a file to execute than to construct a regular-expression etc. to inject the right UUID etc. into the command. I have run into an error while doing this. I suspect it is stems from quote mishandling, or improper escape sequences. (I ran directly from the command line earlier, forgot a quotation mark, and it gave a similar bad result.)
The program in question was efibootmgr. I had a file vaguely similar to this one, named efiboot.Hz:
Code:

efibootmgr -c -g -L "Debian (EFI stub)" -l '\EFI\debian\vmlinuz' -u 'root=UUID=$UUID ro quiet rootfstype=ext4 add_efi_memmap initrd=\\EFI\\debian\\initrd.img'
efibootmgr -c -d /dev/sdb -L "Debian Linux" -l '\EFI\debian\vmlinuz' -u 'root=UUID=1234-ffff-789 ro quiet rootfstype=ext4 add_efi_memmap initrd=\\EFI\\debian\\initrd.img'

Then I executed:
Code:

`tail -n 1 efiboot.Hz`

efibootmgr -v revealed the previous command produced a garbled name and boot options, and most importantly it didn't boot. Manually writing the last line on the terminal did produce the desired effect. I thought I checked the output from tail before putting the back-ticks.
What did I do wrong?

Hello all,
I'm having an issue booting my linux installation after installing refind. I googled the issue but nothing seems relevant to fixing it.
Refind starts up fine and I can see linux (vmlinuz...) but when I select it to boot it says

Failed to open file: install\initrd.gz
Trying to load files to higher address
Failed to open file: install\initrd.gz

It is a dual boot system with Win8. It is an encrypted installation if that makes any difference. Both systems are efi.
How might i go about fixing this? Any pointers and/or relevant threads appreciated

hiiii all

I had installed Windows 7 on /dev/sda1 and /dev/sda2 and then I installed Centos 7.
Since then I cant find Windows entry in the Grub.
And i had tried to use all kind of solution found on the net I still cant see any entry.
I had edited 40_custom script adding:

cat <<EOF

insmod ntfs
set root='hd0,msdos1'

Finally the error in red immediately above pops up.
I searched the net and found a site with an article dated back in 2010 that said to fix the error before rebooting or I'd probably not be able to boot to Linux.
Which I'm doing right now, I've not yet rebooted.

How should I recover from such an error before I reboot.

The site had several solutions depending upon other variables, one of which was to delete and/or re-run something. But none of the solutions seemed to fit my case.

I'm running the Zorin OS 9 Theme on top of Ubuntu 14.04 LTS, an AMD PhenomII 64bit 4 core processor on an ASUS MB. The video card is also an AMD/ATI, hence the need for the fglrx drivers listed above.

I'm not sure if the overwriting of the ATI/AMD driver config files shown above are responsible for the error or not. I did nothing that I was aware of that might have caused it, except close another instance of terminal that was runnning, and a libre office writer window.

Any ideas on how to solve this before I reboot would be greatly appreciated.

TIA
