Ubuntu Installation :: Verification Of The CD (after Burning) Could Not Verify "initrd.lz"

Jan 21, 2010

Just joined the forums as I was downloading Ubuntu Desktop 9.10 (32-bit) from [URL]

Upon burning the .iso to the CD using ImgBurn, the verification of the CD (after burning) could not verify "initrd.lz". I checked that the file was there (it was about 5KB) and continued anyway (probably not a good idea but I figured I could always "Check disk for defects")

After putting the disk in, everything started up great, I selected English and when I clicked on "Check disk for defects" the entire process froze and a multicolored bar of random pixels showed up. I rebooted and tried the "Install Ubuntu" and even the F6 Other Options (checking all the options, then clicking "Install Ubuntu"). I even tried "Test Memory".

Otherwise the menu screen works fine. All F1 through F6 work, the entire help documentation works, but no installer.

I'm sort of stuck now and could use some input since this is uncharted territory for me. The computer does have a version of Windows XP in who-knows-what condition (it won't start up). I don't care about any of the information on the drive and would be fine with wiping it out because that's what I originally planned to do.

Debian :: Make-kpkg --initrd Won't Create Initrd?

May 18, 2010

When I compile a custom kernel with this command: make-kpkg --initrd kernel_image kernel_headers and then install the .deb, there's no initrd in /boot and I have to create it manually. I've thought that the --initrd option should take care about this, but somehow it doesn't.

It behaves like this for about two years at least (since I've compiled my first kernel). Of course, it's no big deal to create it manually, I was just wondering whether do I do anything wrong or whether should I fill a bug report..

Debian Installation :: (USB Boot) On Toshiba Chromebook - OS Verification Is Off

Nov 5, 2014

I just bought a recently-released Toshiba CB35-B3340 Chromebook, and I'm trying to install Debian on it (I want to wipe out CrOS and give all harddrive space to Debian). However, I'm having problems booting from USB. When I press Ctrl+U at boot, the screen flashes back, the computer beeps, and I'm brought back to the same "OS Verification is Off" screen. If I press Ctrl+L to get to what is supposed to be the SeaBios screen, the computer beeps twice and nothing else happens.

I followed steps 1-4 and 8 of this guide: [URL] .... and I just downloaded the amd64 netinstall image from the Debian website and dd'd it to the USB stick.

I've tried two different USB sticks and successfully booted another computer from them, but neither work on the Chromebook. I've also tried both USB ports, since I've heard some Chromebooks can only boot from one, but to no avail.

I have looked into things like ChrUbuntu and crouton, but they look like they just set up a dual-boot or chroot system. I want neither of these, my goal being to have a normal Linux laptop at the end.

Ubuntu Installation :: Does Not Complete Its Installation Verify?

Mar 3, 2011

I'm trying to install Ubuntu 10.10 on a computer that's already running Windows Vista. I used the Wubi installer and it seemed to go through the installation fine (using the desktop, amd64 iso file). After rebooting, I get the dual boot option. However, on Ubuntu start-up, I get a display with the message stating Verifying Installation Files. It seems to go through some verification, but then it gets stuck. I see a bunch of lines with the words "ubuntu ubiquity" with hexadecimal values and regular words. The last hexadecimal values to appear are: 7f2698c50d8e, 7f2698fca815; the last regular word is "_target".

If I quit out of the verification, I am able to get onto the desktop area, but a message appears stating a parted_server crash occured. Also, my wireless connection doesn't work, but I suspect I need to install a driver.

Ubuntu Installation :: Grub2 And Initrd Failed To Install

May 17, 2010

I just did a new install of Ubuntu 10.04 (64 bit) on a system with multiple older versions of Ubuntu already installed. There was a dpkg error during the install with no useful information provided, otherwise the install completed normally. When I rebooted, the old grub2 ran and presented my old boot menu. When I mounted the 10.04 partition to see what was there, I found that /boot/grub/ was empty and /boot/initrd.img was missing. The other boot files were present.

Ubuntu Installation :: Grub4Dos Freezes When Loading Initrd?

May 13, 2011

I am using grub4dos 0.44 but can't boot directly into Kubuntu. The bootup freezes at the step of reading the initrd. Can't copy 'n paste the exact bootup-message but it looks similar to this one, I found on another forum-thread:

Filesystem type is fat, partition type 0x06 [Linux-bzImage, setup=0x1400, size=0xcff87] Unlike the guy who posted the two lines above, I installed Kubuntu on an ext3-partition (hd0,5), (which is /dev/sda6 in Ubuntu) and without an own bootloader, since I wanna use grub4dos instead of grub2. The installation is fresh - the initrd-file shouldn't be broken. My menu.lst looks like this:

Ubuntu Installation :: Create A Custom Install Kernel And Initrd?

Mar 26, 2010

I need to install Ubuntu on approximately 50-60 netbooks. None of them have CD drives, and I don't want to have to install them individually, walking around with a USB stick. I figured the fastest way to install on so many machines is to use a combination of apt-cacher (http://www.debuntu.org/how-to-set-up...ith-apt-cacher) and netbooting. I have successfully booted one machine to test, but as soon as the kernel comes up, support for the network interface is gone. Specifically, the "atl1c" module is not included on the netboot initrd image. Also, I would like to try to use preseeding, and I need to get that onto the initrd as well.

So, to summarize my question: How can I create a custom install kernel and initrd? I have a feeling it's related to the "debian-installer" category in the package repository, but I have not found any good documentation about doing this.

Fedora Installation :: Exclude The Kernel And Initrd From Being Updated?

Jan 21, 2009

I had to uninstall f10 from my system because it would lock up my system anywhere from 1 to 5 minutes into using it and noone could tell me why.

NOW, I put 9 back on my system and after it updates everything, it locks up again. it does give me the option of the new kernel and the original install's kernel and if I choose the original to boot with, I don't have any problems.

SO, is there any way to fix it, OR to exclude the kernel and initrd from being updated?

Ubuntu Installation :: Edit ISO Image Before Burning To CD/DVD?

Jan 6, 2011

I plan to make multi boot linux DVD, with help of SarduCD software, so, I have one question. configured Linux ISO image is not as I would like, I would like to change appearance and to add some softwares, in that way I will not have to change and install it every time I use live DVD in the future. I have now already installed 4 linux in one DVD but evey time I use it, I must change and install softwares, now I want to install on DVD the newest version of Ubuntu and Kubuntu, beside puppy and some other distros, and my question is: how to edit K/Ubuntu ISO image with aim that I don't need to change anything anymore after I burn it on DVD?

I suppose I should unpack and edit ISO image (add softwares and change appearance) and after that pack it again in ISO image. Maybe it is easier to burn Ubuntu to CD, to change and install what I want, into Live CD, and then to extract such Ubuntu to ISO image, then it would be ready to burn it together with other distros into DVD?
