CentOS 5 :: PXE Boot Fails With "loader Received SIGSEGV! Backtrace"?

Aug 3, 2010

I have a Sony Vaio PCG-5A1N (built for Japan) which has a malfunctioning CD-ROM. The bios doesn't support USB external CD-Drives and it doesn't have any USB boot either.The only method, I am left to work with is the PXE boot. I have finally setup a PXEBOOT on another CentOS server and everything works fine all the way to choosing language etc....but after it grabs images/stage2.img this is what it gives me:

loader received SIGSEGV! Backtrace:

Ubuntu Servers :: Install Fails At Grub Boot Loader

Feb 26, 2010

I'm using the RAID1 setup, which is configured in the BIOS, as it is a HP Proliant server. i have 2 500GB hard drives configured in a mirror. when booting the install, it recognises this, and deals with it fine.

The problem is, when it gets to the section of installing the grub2 boot loader, it just stops and gives me the "ubuntu installer main menu" where if i select grub boot loader install it just loops back, and if i select LILO installer, it errors, saying an installation step failed.

It has the option to skip installing boot loader, but then, can i get it to boot a different way? can i boot manually into the server install and then install GRUB and hope it works? can i install grub1 rather than grub2?

Feb 17, 2010

I have installed the ubuntu 9.10 and the pc already have 2 win 7 OS and 1 win xp I installed the ubuntu from win xp every thing go just fine but in win 7 boat loader it detects the 2 win 7 OS , previous windows ( the xp )and the ubuntu which fails to load from win7 boot loader ( the first problem ) but it is present also in win xp boat loader so when choosing older windows the win xp bootloader let me choose between windows xp and ubuntu which works fine when choosing it the ubuntu bootloader appears with ubuntuubuntu safe modewin7 bootloader

the second problems that choosing win 7 after restarting the pc from ubuntu fail to open it begin loading with the windows logo and then just shutdown the whole pc as if i have unplugged it! the only way to let it open is to choose older windows>>> ubuntu >>>> ubuntu bootloader >>> where there is win 7 bootloader option it returns me again to win 7 bootloader but this time the windows load complete ( mostly but may shut down also!)

Ubuntu Installation :: Vista Multiple Boot - No Boot Filename Received - No Bootable Device

Jan 2, 2010

i had a working multi-boot system, vista on sda1,2; swap sda3; ext=sda4; ubuntu sda5; fedora sda6; data sda7 - i mount the data partition when using all of the linux releases so i don't have to have multiple copies of music, docs, etc. everything has worked fine until yesterday. i tried to install fc12 on sda6, replacing fc11. it required me to format sda6 as ext4. i wasn't sure where i had grub installed, but have a backup of menu.lst in data (sda7), so figured i could let it install to mbr or wherever it wanted to by default. when the install completed and i reboot, i get a black screen and these messages: CLIENT MAC ADDR: 00 19 XX XX XX GUID: XXXXX PXE-E53:

No boot filename received
PXE-M0F: Exiting Intel Boot Agent.

No bootable device -- insert boot disk and press any key I tried reinstalling fc12, same exact errors. I then thought maybe the problem had something to do with ext4 partition mixed in with ext3's, so i installed mepis on the sda6, and let it write grub to mbr (i think, not really sure where it wrote it). anyway, i still get the identical black screen. no grub type menu or anything. the screen used to show "DHCP for a few seconds", but doesn't anymore after i disconnected the ethernet cable.........

Ubuntu Networking :: 10.04 - Gobi Loader Fails On 10.04 RC - Worked On 9.10?

Apr 26, 2010

[10.04]-Gobi Loader Fails on 10.04 RC, Worked on 9.10? I was using a program called "Gobi Loader" to manually setup my Qualcomm 9212 3g internal USB modem on my Verizon Wireless Gateway LT2016U NetBook. Gobi Loader program loads the modem's firmware so it is usable by Ubuntu OS. This worked fine on Ubuntu 9.10, but on Ubuntu 10.04 RC when I run Gobi Loader it just hangs. I've Googled for hours and have not found a solution to this issue. For me it is a big issue as in Ubuntu 10.04, my 3g access is not working. (I'm paying Verizon Wireless $60 dollars a month for 3g access my Ubuntu 10.04 can't use.)

The only option I see now is to install Windows(R) XP, then reinstall Ubuntu 10.04 and dual boot. I would have to boot into Windows(R) XP first, the soft reset and boot into Ubuntu 10.04. (but this is not something I wish to do) This Qualcomm 9212 3g internal USB modem is quite popular in NetBooks, and I can't be the only person in the universe who is using Ubuntu 10.04 on it so there must be some way to make this 3g modem work on Ubuntu 10.04?

CentOS 5 :: Ddclient Fails To Start At Boot / What To Do?

Jul 9, 2009

I have installed ddclient for use with dyndns.org.

I can manually run it from the prompt with /etc/rc.d/init.d/ddclient start
and can verify that it works by checking that my IP has succesfully been changed at dyndns.

When I reboot though, during the startup, I get the following:
Starting ddclient: /bin/bash: ddclient: command not found [FAILED]

I am very new to Linux, so I am not sure what or where I should be looking to solve the problem. It seems to me that it must be looking in the wrong spot for ddclient, but I don't know what to check or change to point it at the right place.

CentOS 5 Hardware :: 5.3 - 4Gb RAM Added - Boot Fails - Can't See Login Screen

Jul 9, 2009

I have a Dell precision 380 (system specs can be found here: [URL]. My system is set-up in dual boot configuration with Windows Xp x64 on one side of my HD and CentOS 5.3 (64bit) on the other. My system came with 2Gb (2 x 1Gb) of RAM and I recently wanted to upgrade. I bought 2 x 2Gb ELIXER DDR2 667Mhz RAM. I carefully added the new sticks to my motherboard, booted up windows via bios which noticed the new RAM was present. All seemed well.

However, on rebooting the system and entering the CentOS boot phase, after the boot phase (eg starting program... [ok] etc) but before the login screen my screen goes black / blank. My system has an ATI FireGL v3100 graphics card, I checked out the technical info on this and it should be ok on 64 bit linux. (See: [URL])

CentOS 5 :: Unable To Boot After Fixing Partition Order In Fdisk - Grub Fails

Apr 29, 2009

It seemed that it would be simple enough: take the 'f' option in the expert menu of fdisk to put partitions in order after a gap had been created by a deleted partition and then make corresponding changes in /boot/grub/grub.conf because the root partition was shifted.

Well, it didn't work out that way. No matter what I try, I either see the error 15 at Stage1.5 or the error 28, which is even stranger (file does not fit into memory). All this before I even see a grub menu. It just does not get that far.

Does anyone want to take as stab at guessing what might have happened here and whether I have a chance at recovering without having to reinstall? I can provide concrete data, if anyone would be kind to give it a try. Hoping that this is a known problem and something can be guessed from what I stated here but I can be as specific as needed, just don't want to generate noise if there are no takers.

***Droppping you to a shell, the system will reboot when you leave the shell
Give root password for maintenace

After I log in with the root I get the message mesg: error tty device is not owned by group 'tty' Can the forum tell me how to troubleshoot this issue so I can boot back up again? I have 2 harddrives in this server and only 1 drive was detected when I first installed CentOS. The error first appeared when I mounted the 2nd drive at the mount point /UserGeneratedData. drive was formatted with ext3 before mounting and did not have any data on it I don't want any software RAID if thats what seems to be going on with "VolGroup00"

CentOS 5 Hardware :: Uhhuh. NMI Received For Unknown Reason 30?

May 20, 2010

Im having a hanging problem with a HP dl160g6. uname -a shows:

The server was working fine since November �09 until a month or 2 ago.Sometimes (almost daily now) the machine hangs and shows the front "health led" blinking red.The services do not respond,locally i can see the login screen but when attempt to logon it freezes (the same happens with ssh).2 weeks ago i open a case in HP and the support sugest that the problem is in the X server (??), since then the system starts in runlevel 3 but the problem continues. A week ago open another case, on Tuesday make a BIOS upgrade but today in the morning the server hangs again.

There�s no strange messages in log files but... after the Tuesday hungs (before the upgrade) i can see the error msg below (thanks to the change to console mode):

Uhhuh. NMI received for unknown reason 30.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?

Uhhuh. NMI received for unknown reason 20.Dazed and confused, but trying to continue.Do you have a strange power saving mode enabled?

Ubuntu :: Errors Received When Trying To Boot From USB

I have a relatively new computer that won't boot Win 7. After going through a lot of tries, I got a suggestion that I try to boot using Ubuntu from a USB flash drive ( since I can't burn a CD).

I followed the procedure to put the necessary files (Version 10.04 64 bit if I recall correctly) on the drive and tried to boot using it.

I got this message:

When I tried to boot again (from the above) I just got the second message (No DEFAULT etc.)

pxelinux.0 was taken from RHEL4, but I've got image and trying to boot RHEL5. Maybe there is something?

CentOS 5 Server :: DHCPD On ETH1: Distribute ETH0-received DNS?

Sep 14, 2009

this should be trivial for all you big sysadmin guys My box is a firewall/gateway. ETH0 is on the Internet-side, and is fully auto-configured (DHCP client) from my ISP. ETH1 is on the LAN-side, has DHCPD enabled, and I route the traffic to/from the Internet via iptables (NATting, of course). Everything works pretty good, except for the DNS-server assignment via DHCP: how can I configure dhcpd.conf to assign the SAME dns-server I receive from my provider on ETH0 to all my PC on ETH1?

Debian :: Grub Boot Loader On A Dual Boot System?

Dec 16, 2010

This is the third time I try unsuccessfully to install Debian as a second OS on a hard drive. When it gets to the end of the installation process the installer asks whether I want to go ahead with the Grub Boot Loader, I choose yes. The end result is however that I can't boot that partition within the hard drive -- i.e., Debian. Can someone tell me what is going on? Should I not use the Grub Boot Loader when I have more than one operating system on a machine? Should I not install Grub on the Master Boot Record (MBR)?

Fedora Installation :: Repair To The Grub Boot Loader To Boot Into Win 7 ?

Oct 23, 2009

I have XP, Win7 Pro and F 11 installed. Before I installed F 11, Win 7 boot mgr was working fine. I then installed F 11 and I went to System/Admin/bootloader to edit it and it wouldn't bring up the boot loader. In the attachment was the error msg. Now my only option when I boot up is F 11.

I do not have access to the Win 7 DVD only the F 11 install disk since I am on a fishing trip and need to use Win 7. How can I repair to the grub boot loader to boot into Win 7?

Fedora Installation :: Multi Boot System - Set Up The Boot Loader ?

Mar 18, 2010

I'm trying to install Fedora onto a computer that has Windows XP on the first of two SATA drives. Windows 7 is on the second drive.

I installed Fedora no problems on a 14 gig free space I created on the first drive and told it where and what my other OS's were. Fine so far. I didn't tell it to overwrite the MBR on the XP (first) drive. I took the second option which I "think" put the boot loader on the fedora partition.

All good - till I rebooted and I just saw my Windows 7 loader with my options for XP and Windows 7 but no Fedora.

So, if I overwrite the MBR on the first drive, will that mean I can't access my Windows 7 installation?

How SHOULD I set up the boot loader?

Ubuntu :: Dual Boot - Changing Boot Loader Between Disks?

Jun 17, 2010

Here's my current setup:

Disk 0 (500GB): Windows Vista
Disk 1 (1TB): Windows 7
Disk 2 (160GB): Ubuntu

My boot disk is Disk 0. Currently when I turn on the PC, GRUB loads from Disk 0. I can then choose either Ubuntu or Windows Loader. If I choose Windows Loader (also located on Disk 0), I can choose to load Windows Vista or Windows 7. I like this setup, but I would like to move the loaders (exactly as they are) to Disk 1 so that I can format Disk 0.
