Ubuntu :: Pae Kernel - Selection From List Appears After Grub Load?
Aug 23, 2010
I am currently running 9.10 ubuntu (gnome). I have a dual core intel chip at 3.00 ghz. My mobo is an ASUS P5ND2-SLI. My mobo will support up to 8gb of ram. Now, as we all know, 32-bit os/kernel will only support like 3.2gb, and 64-bit like 4gb. I'd like to install a pae kernel so I can get the most from my mobo, but honestly, I don't have a clue where to start looking for a pae kernel. I'd like to be able to select it from the list that already appears after the grub loads, and if I like it, be able to remove the rest from the list, or just make it default.
Question, in CPU-G, it says my architecture is i686. I don't know if that's the os/distro, or the kernel itself. it also lists the GCC version as 4.4.1 and Xorg as 1.6.4. my current kernel is Linux 2.6.31-22-generic. Again, I'm trying to find a pae kernel, but I don't know if my os/distro will make a difference, if the architecture is the kernel or os itself. I am still fairly new to ubuntu, and I must say, I've made the switch completely from windows.. which blows...

I have installed Debian a few times now (and other distro's), so I'm fairly used to installing linux. I'm not used to installing it on Apple hardware (back in 2009 on my laptop I had some issues that were solved rather quickly, but that's about it). Now I'm installing Debian Squeeze on a new (well, bought today, but it is the previous model: iMac 11,2) desktop iMac.
Installing goes well (resizing partition, rEFIt, booting Debian 6.0.1a netinstall CD, installing packages etc.) I followed a tutorial [URL] to install grub explicitly with force after installing and running gptsync. Everything went according to the tutorial and I rebooted to be welcomed by rEFIt and then grub: perfect!
BUT when I chose Debian in the grub-selection list, I only see a few lines of starting the kernel, and then my screen goes all black. A few seconds later I hear a sound, and iirc it's the sound of gdm prompting to select a user. I cannot switch to a TTY and I have to use the power-button to shut the system down.

I'm trying to boot into 10.04, but all I see is the purple background. I never get a login box to load the desktop. I've managed to gain access to the desktop, using the command line from the recovery console, only to see various warnings about gnome applet failures.

I locked the screen, came back, typed the password, screen remained black, though cursor was visible and moving. Nothing I could do to rejuvenate the screen. Had to switch to tty6, sudo shutdown -r now. Then, on reboot obtained kernel selection, it proceeded to displaying kernel messages, but froze on sdb, after 3 secs. I figured it was the usb, so turned off, removed usb cables to external hard drives, but again it froze saying something about firewire mouse, the mouse is also usb. I tried several times, but no matter what kernel I chose, I couldn't get it to boot. So I loaded puppy live cd, but now it can't access some parts of the disk. I was running utorrent and the folder with partially downloaded files can be accessed but there's nothing there (there was), and some folders can't be accessed at all.

installed Python 2.4 and then removed already present Python 2.6. After restart, when i selected the working kernel, that white ubuntu symbol splashed and screen went black with two small lines at the top.. it doesnt go beyond that. Please help me. I tried selecting other kernels. It did not work. I used "nomodeset" by editing the the kernel at the grub..

I downloaded the Ubuntu ISO file and burned it to a CD-ROM. Booting from the CD on my laptop I select the language and selection screen appears with all the F1-F6 options below. I've tried all the selections and options through the F keys but that's as far as the install will go. My laptop is a Dell and it's only 3 years old with plenty of memory and HD space.

Over the past few days I have been trying to install an older kernel (kernel 2.6.28.1) on ubuntu 9.10 64-bit WUBI installation. I compiled, installed, and updated my grub for the kernel. When I reboot, the grub menu correctly gives me the option of booting into the older kernel but when I do so I receive the following error message:
error: you need to load the linux kernel first.
I am at a complete loss on how to fix this. I even downgraded grub but I still get the same error.

I recently removed Winblows Vista from my laptop and replaced it with Kubuntu 10.10 (I left the recovery partition on there, just in case). When I turn on the computer, the GRUB menu appears, I press enter, then a little flashing underscore appears on the screen in the top left hand corner. After a few seconds, the Kubuntu logo appears and I can log in.But yesterday I replace Kubuntu with Ubuntu 10.10. The Boot process is the same, but the little flashing underscore in the top left hand corner flashes for about 10 seconds longer then Kubuntu 10.10 did, and then a few paragraphs of text appears for a few seconds, then I am logged in automatically.Is this "unusual" boot process anything to worry about, or am I just being a noob.

So I have been using Ubuntu for the past couple of months using Wubi, mainly because my parent's are afraid that I'll screw something up on the computer if I partition the hard drive and stuff like that. And Today I installed the latest updates for 9.10, asked me to restart the computer, and now whenever I try to boot using the latest kernel GRUB keeps telling me to "Load kernel first". The funny thing is that I can boot with the older kernel fine, But I would really like to get the lates updates, which I can't using the older kernel.

After installation of Ubuntu 10.10, grub loads and has the right menu list. However, Ubuntu doesn't load and I get an error message of :Gave up waiting for root device. (with a list of common problems)There is also:ALERT! /dev/disk/by-uuid/1584598e-b8e5..... does not exist.

I unfortunately remove "some" softwares on my OpenSuse10 (preinstalled on my laptop, without cd driver) cause I was running out of space on hd. Icons starts to dissappear ...
Then I have only the Grub 0.97 shell that appears and to use to solve the problem... tried to boot kernel, but said that it "must be loaded before boot".
In the Grub 0.97 black window I have two lines :
I press "b", to boot with the First line : kernel (hd0,2)/boot/vmlinuz ... but the window turns blue and said "all data would be lost", so it shut down the system automatically to avoid this.
I press "e" to edit the command in the boot sequence for the same line, but don't really know what to tell Grub to do.
I must get my important datas back on my hd before "Restore to factory settings" (the last option). Any solution ?
Maybe it is a step on a solution ?
From [url] I downloaded linux kernel 2.6.27.27 on a usb memory stick. Could it be useful ? how to ?

I tried to update to 2.6.31-20 kernel but I think I messed it up, because when I click on it in the GRUB it starts to load but then it goes back to the dell boot up screen and I have to use the older one in order to get onto ubuntu. Is there anything I can do to fix this?

I am trying to create an array that will allow me to print a list after selection such as:
1) Location A
2) Location B
3) Location C
Would you like to print selected locations? Print I have no idea how to approach this problem and don't know whether Perl, Bash or shell script would be the most useful in this particular situation.

After certain system-wide changes, like kernels updates, I obtain grub prompt on restart. However, if I put the hard drive into another computer (b), it boots up fine. Since, however, I use the present computer (a) regularly, I only use b to purge and reinstall grub using the chroot method. However, doing so every time is time consuming; and I cannot change anything in the defaults and run update-grub without obtaining a grub prompt on restart. How do I fix this?

Before I had to re-install, because I ran out of space on my partition and could not grow it, I had a setting that would not show the selection screen for the different kernels at start up.
Does anyone know how to set the start up as such that the selection screen does not show?

Ubuntu hangs at start up.Im running 10.10 from a wubi installation - without any problems since. Now, I select the kernel, do ENTER, then I get the blinking big dos-like cursor (still normal)but when it should show the list of "checks".( I dont know how this is called where it checks services, battery state and comments everything with [OK]) it suddenly hangs. All I get is a small blinking cursor, but not more. I need to power down and turn my computer on again, then it usually works.

But when I install new updates for Ubuntu and restart my computer to apply those updates.... a new Ubuntu with different number appears on the list of the operating systems that I need to choose from
[Code]...
does this mean every time I updated Ubuntu I'll have additional OS on my device?

Installing 10.10 RC dual boot with Win7. Is there no place in the installer to specify where Grub will be installed? I don't want it installed in the MBR I want it in the partition with / (I usually only create two partitions for Linux / and swap). I prefer to chain load grub from my windows bootloader.

I've tried to find it on google, but I want to have my OS Screen Selection to have a cleaner look than what it currently looks like. I understand we can edit Grub 2 but nothing I've found shows me what to edit into the file. I have all of the files I just need to know which one to edit and what to put into the file so my OS selection looks better

I have set the kernel selection time out to 3 seconds. However, sometimes it just hangs indefinitely on the kernel selection screen until I manually select the kernel. This is bad news since it is a VM started up from a script and _has_ to start automatically. The VM is a re-constructed cloud backup made by rsync and re-running grub.
Is there any way to force Ubuntu to NEVER, under any circumstances, not time out on kernel selection.

I'm having some problems with my wireless connection. I'm on Ubuntu 10.04, on a HP ProBook 4520s, with a RaLink RT3090 wireless network card. I installed the drivers (hopefully correctly), the wireless seems to work correctly, it scans and finds networks, but when I try to connect to one, it times out after some time, while still attempting to connect. I also have a wired connection that works correctly and without problems. Other computers that try to connect to said wireless network manage to do so without any problems, so this has left me a bit baffled, since, like I said, everything seems to be in order.
I'm a new Ubuntu user, so please tell me what other information I need to provide in order to easily and successfully facilitate troubleshooting this, because it is, as you can imagine, quite aggravating, having a laptop that needs to be connected to the internet through a cable.

Finally got a dual boot on this laptop the way I liked it (LOVE my Win7, really like UBUNTU for certain things like getting booted and on the net fast...great). As I was editing and rebooting the GRUB settings UBUNTU got it's updates and installed (including one on GRUB that I hadn't seen before - WITH WARNINGS). Now I can't seem to get this last entry out of the boot menu: vmlinuz-2.6.31-14-generic. It has all this listed now (had dual entries for everything like mem test before):
vmlinuz-2.6.31-17-generic
vmlinuz-2.6.31-14-generic
Windows 7
I got rid of the extra entries like memtest and all using: sudo chmod -x /etc/grub.d/20_memtest86+ and such variations..still though I got one stuck in the boot selections. It won't remove the old linux vmlinuz-2.6.31-14-generic build entry from GRUB (and they both point to the same place). It has a -14 and -17 entry in it now. Like I said both load to the same mount point.
I mean I removed like five extra entries from GRUB using that command after the update (and had done it before about two months ago) but the linux vmlinuz-2.6.31-14-generic selection won't leave the GRUB selections now. I really thought I had it figured out to the bomb having my laptop dual booting before, just didn't like how UBUNTU used my disk space by default last time so I decided to rebuild the laptop.

First let me describe my system setup. I have windows, ubuntu 64 and ubuntu 32 present. I upgraded the 32 bit version to 10.4 with no problem. After upgrading the 64 bit version is when the problem occurred. I believe it has to do with the grub.cfg file. When I would choose the 64 bit version the screen would just go black, no furthur action. After making a few changes to the 64 bit selection in grub.cfg i come to a screen that says c to continue, s to skip mounting, and m for manual mount. Pressing s gets me in. Here is a copy of my grub.cfg.

I have had a working ubuntu 10.10 installation for about 2 months. I had it set up really nicely with my TV card and xbmc. I was really happy until I tried to boot it the other day to show a movie to the Mrs. All I seem to get is a flashing cursor after the initial grub selection. This is the same for both recovery mode and normal. I have booted it after editing the boot selection to removed the quiet splash and it seems to hang after a line that says some thing like "usb 1-4.2: new low speed USB device using ohci_hcd". The machine boots fine in to the Windose partition or in to a live CD.
I have done a bit of searching and I am struggling to find a good step by step troubleshooting guide. I dont really want to blat my setup but it would teach me a lesson about documenting things and blindly doing upgrades. I have included the results from my boot info below in case that points to anything.

Im using the following system setup: When I boot my business computer, I can choose between 3 setups, 2 Windows XP, 1 DOS. I installed Ubuntu with 1 Windows XP system which looks something like this:
System 1 (XP)
System 2 (XP) --> after selection, Im able to choose between the XP system and Ubuntu on a new screen
System 3 (DOS)
Now interesting for me is obviously System 2. After I select System 2, I can choose between XP and Ubuntu. After I select Ubuntu, I come to another screen, where I can choose again between 4 Ubuntu entries with different kernel versions (including their recovery modes) AND both XP systems (yes, again). I installed Grub Customizer. I removed all the XP entries and all but 1 Ubuntu entry from this screen. I also set the timeout until booting Ubuntu on this screen to 1 second to start as quick as possible and Ubuntu boots fine.
My question now is, is there a way to skip the screen with former kernel and XP selection and boot Ubuntu directly after already choosing (between XP and Ubuntu) on the first screen? I know, 1 second "waiting" is not too bad but skipping the screen completly would be superb.

I downloaded Ubuntu 11.04 yesterday. The ISO allowed me to install Ubuntu using Wubi and it worked just fine in Windows (I used a virtual drive to mount the ISO). I liked it enough to want to replace Linux Mint on the Laptop with it.After a LOT of trying, I was finally able to make the liveUSB of Ubuntu 11.04 32-bit version.[URL]isplays the boot menu and if I select 'try Ubuntu without installing', I am greeted with a blank screen which just does not go away until I hard reboot the system. Also, the grub I am getting is NOT the purple one which usually is the default; instead, its a dark screen with a black-n-white titled Ubuntu logo. So the question of using the NOMODESET doesn't arise at all. I am using Dell XPS 15 with dual OSes - Linux Mint and Windows 7. Both Mint and 7 are 64-bit OSes but I am trying to install Ubuntu 11.04 32-bit version.

My USB sound card used to work perfectly, but after i unplugged it, there seems to be a problem. When it is unplugged it is in the multimedia device preference list, but it is greyed out. When i plug the sound card in, nothing happens to the greyed entry, instead a new device shows up with the same name.
When press test on the new entry, it works fine, but it's like pulseaudio dosn't recognize the USB sound card, and the sound just comes out of the internal speakers. Also, if i move the new entry up in the list, it has none effect at all. Sound still comes out of the internal speaker. Does anyone know how i can fix this?

I installed bt4 alongside my windows and fedora13 partition, but my fedora won't boot after that, so I updated grub to 1.96, but still fedora13 won't boot, it displays the error, "You need to load the kernel first". When I try to boot fedora from grub command line, linux (hd0,6)/boot/<TAB> it does not show any entry, although my fedora partition is intact with vmlinuz and initramfs inside the /boot directory. BTW (hd0,6) is my fedora13 partition, file system on fedora13 is ext4, while on bt4 it is ext3.
