Ubuntu :: Changed These BIOS Settings But Now Won't Boot?
Oct 16, 2010
Long story short, I changed these BIOS settings (and changed them back), but now Ubuntu won't boot: SATA RAID/AHCI Mode: from Disabled to AHCI
Onboard SATA/IDE Ctlr Mode: from IDE to AHCIThe last thing it says is "Init: ureadahead-other main process (nnn) terminated with status 4". Booting off an Ubuntu CD and entering Rescue mode gets me to a shell; the file systems are still there, but Reward for first solution (other than reload): $10 Starbucks card!

Is there some workaround by changing grub settings other than rewiring the hard disks or changing in bios..
1. my bios is getting reset (low battery)
2. my hard disks are sata and ide, so the ide one is loaded as hd1 by default, cudn't find any way to change that..

I currently have a Windows XP OS which i want to dual-boot with Ubuntu Linux 10.10 . I put the disk in the drive and chose the option to install Linux through Windows. But it hangs in the middle. I am also unable to change my BIOS settings due to which i can"t change my boot preference. My first Boot is the HDD. I want to change it to CD-ROM. Any suggestion? I also have another PC where i can boot through the CD...I tried installing there by booting from the CD but i get this error message after seeing the purple Linux screen with the loading dots. "(Process:286):Glib warning**:getpwuid:failed due to unknown user id (0)
P.S.- I am not able to see any options while the boot is going on

Server has DQ35JO board, 8GB memory, multiple SATA hard drives. It was happily running Fedora 10, and Fedora 9 before that. I downloaded and burned the F11 DVD, booted it, did an install which is:
-- delete the LVMs
-- create a 200 MB /boot on ext3, the rest of /dev/sda on ext3 as /
-- reformat the swap partition on /dev/sdb1
-- leave the other file systems alone (they are all ext3)
I chose no optional packages and let it install. It finished normally and got to the "click to reboot" screen. Now, my server is completely bricked. When I power it up I get a blank screen with a blinking cursor. I cannot even get to the BIOS, or boot my Fedora DVD, much less boot the boot drive.

Ubuntu from version 9.10 to 10.04 today, and now all of the window settings (maximize, minimize, restore, close) have been moved to the left side of the border. I can't seem to remember how I did it, so can somebody please tell me how to move it back to the right side? It's not serious but I like it on the right side

I'm successfully dual booting and running Windows XP and Fedora 11 (with EVERY recent update installed), everything works fine EXCEPT that I cannot get both System times to synchronize.. Evey time I run Fedora I find the system time is always an hour different to Windows. Evert time I correct the system time in Fedora it affects my BIOS time settings. If I then go into Windows I first have to go into the BIOS and correct the BIOS time setting by one hour before I get the correct time in Windows........ Nothing is wrong with my Windows side of things, I know this because if I don't log into Fedora then my system times stay correct, only when I correct the settings in Fedora (which are always an hour out) do I get my BIOS changed. Also in Fedora, although I live in the UK (London) Fedora ALWAYS DEFAULTS TO Guernsey, no matter how many times I correct this to LONDON, Fedora always defaults back to Guernsey.... Has anyone else experienced this as I'm sure it's a Bug in Fedora, surely it shouldn't alter my BIOS settings, should it ??

Im trying to test out Ubuntu while running Windows currently, once i got the ISO image installed into my USB device by following the steps on the Ubunto site, i rebooted my PC and tried to get into BIOS to change the setting to boot through the USB device.
but i was unable to open BIOS.
this is all i saw in the bottom right side of my screen as far as commands to open some thing before my PC would boot through my Cdrive and load Windows.

Is there something I can do to get a Linux Distro to install right the first time. I have the same types of problems with Mandriva Ubuntu and Fedora over and over again but not with a OS you pay for. Is it time for BSD?

I've got two laptops running Ubuntu. Both have had Lucid installed from the live cd. I have upgraded one of them to Maverick. Both distributions are running great after they boot up, but I haven't experienced any faster boot times with either distibution. Both boot to Bios and then the screen goes black with a blinking cursor in upper left corner of the screen. The black screen remains for 30 to 45 seconds and then I get the Ubuntu splash screen for maybe 5 seconds, and then desktop. Why am I not seeing faster boot times? I realize 45 to 60 seconds is good compared to other os's, but I anticipated much faster boot times. Shut down on the other hand is quite fast at maybe 5 to 10 seconds. Does anyone else get this black screen on boot? Seems like wasted time cause I can't tell what's going on during the time there is a black screen. This is not a real big deal breaker, as I don't reboot very often, but I just wonder why bootup isn't faster.

Well today I decided that I couldn't wait for the offical release of 10.04 LTS, so I upgraded from 9.10 to 10.04 LTS Beta 2. After realizing that many problems had come with that update, I decided to just format my Ubuntu partition and reinstall it. Somehow my GRUB stopped working from when I formatted Ubuntu, so I whipped out the old Toshiba recovery disk for Windows Vista 32bit. After many attempts to have the recovery portion of the disk fix all of my problems and seeing no results, I decided that reinstalling Ubuntu (and GRUB) might make everything all better. Well it didn't. Grub shows my Windows partition but fails to boot it. After selecting it, it goes to a blank screen and stops responding. And to add to all of my problems, my BIOS has changed slightly. It no longer shows/or responds to F2 or F12 when I tried to give another try at that Toshiba recovery disk. That kinda sucks since I can't choose what to boot. Please help me!! I really don't want to have to format my entire hard drive and try to install Windows Vista again (Not that Vista is anything anyone should love) I have many expensive programs that can only be activated a certain amount of times. I don't even think that I could reinstall Vista since my BIOS won't let me boot the CD/DVD drive.

1: I changed some settings in "local security", about file permits or something, and now I can't run Yast to fix it, not even see it. Neither can I add or remove any software. And the ugliest part is that I can't even shut down the pc. It pops up a shaking error message about authentication stuff. How do I fix this?
2: It also throws en exception whenever I try to install my monitor's driver, a HannsG, which is an .exe file. I was told I should run .exe files through Wine, but this wont work either. Is there another -and more appropriate- way to execute this files?

I deleted the firewall files "K09SuSEfirewall2_init", "K01SuSEfirewall2_setup", "S11SuSEfirewall2_setup" and "S01SuSEfirewall2_init" from "/etc/rc.d/rc5.d" in order to disable the firewall when rebooting.
As a consequence all network services are not working. I can't connect to any other machine nor to the internet.
I rebuilt the symbolic files based on the ones for runlevel 3, but still no network services are available.
Any suggestions how to make it work again? I'm using Suse 11.3.

I have installed Ubuntu 10.10 Minimal on a 2GB USB using CLI and it is working very well after adding a few applications. But this USB will be used only on machines other than my own - likely with Windows as the only OS. And it is not comfortable for me to go into the BIOS of a strange machine to change the order of booting and afterwards go back to reset the order , especially with the owner looking on, obviously worried, and wandering whether his machine will still be working!
So my question: Is there any way to boot from a USB without having to go into the BIOS? code...

I understand this is not directly an ubuntu issue, but this arose as I was trying to install ubuntu, so I'm hoping some kind souls on here would be good enough to help anyway.
I've in the past installed ubuntu on to my PC using a CD, but this time I thought I'd try creating a USB startup disk.
I was required to set up the BIOS to change the boot order so I can boot from the USB flash drive.
The problems arose when I pushed the 'DEL' key (the correct key for my motherboard) to access the BIOS setup. When doing this the computer completely froze and would not progress any further to boot. It would still boot normally from the HDD provided I didn't try to enter the BIOS.
Looking on the internet for a solution I tried using the motherboard jumper to reset the CMOS. Now I can't boot up the computer at all. I get a message saying 'CMOS checksum error - Defaults loaded' then it asks me to press F1 to continue. I try this, but nothing happens. Clearing the CMOS has made things worse as now I can't get the computer to boot at all.
Have I killed my motherboard somehow? I've tried using a different keyboard (one USB and the other a USB keyboard but with an adaptor to connect it to the P/S2 port).
On further investigation any key press from the keyboard is enough to freeze the computer at whatever point.
My motherboard is an WinFast NF4SK8AA with AMD Athlon processor and 4Gb of mem.

I was wondering to restore on old laptop to working order. This laptop is an old early 2000's Sony Viao, which I found in the trash. Still powers on, and can boot the latest Ubuntu LiveCD. The issue is that it did not have a harddrive in it, and I really do not want to shell out money for a drive for a laptop this old, but would still like to bring it back into service as a thin client or general purpose web/email terminal. The BIOS does NOT have a USB boot option, and every tutorial I have seen requires that in order to boot Ubuntu from a USB stick (which is what I do have). What I am wondering is, is there any way to just keep the LiveCD in the drive and use that to boot the kernel, etc, and then have it look for the rest of the filesystem on the USB stick?
