CentOS 5 :: Unable To Boot Windows After Installing CENTOS 5.4
Nov 18, 2009
I've Got one Problem with My Computer soon after success installation of when the boot-loader ask me to choose OS at CENTOS 5.4, multi boot boot-loader if i choose windows then computer tries to boot windows but fail and give the error message that there is a problem on reading the hard disk, But when i restart it and start with LINUX then computer start successful with no error message, now i do not know what to do cause i need to use Windows and all my programs are in windows..
3 partitions (in order): Windows 7, CentOS and shared data partition.
I need to increase the size of the Windows 7 partition (c:windowswinsxs seems to be something not easily remedied).
GParted didn't work in moving things around (bad sector) so I wiped out its partition (# 2 out of 3) and I was able to increase the size of the Windows 7 partition (I can reinstall CentOS easily and not much work lost).
Except ... no more grub menu (unsurprising). This incantation does allow me to boot into Windows 7.
Is there any way of rebuilding the grub menu short of reinstalling CentOS (5.5)?
I had Windows XP Pro 32 bit and CentOS 5.4 installed on my Dell M6400 laptop and life was wonderful. Until I had to reinstall Windows. In the process, I reformated the C: partition of the drive where the Windows operating system was installed. I was careful NOT to reformat anything else. Now I cannot boot CentOS. The drive that has both the Windows and CentOS still shows the same partitions as were there before I reinstalled Windows, namely:
NTFS (C:) 171.82 GB /boot 102 MB (F:) 60.96 GB
is where my CentOS partition has all of my linux data and apps. I assume /boot should be the boot partition for CentOS I use Acronis OS Selector to show the partitions to boot. Now CentOS doesn't show as an option even if I go through the process of trying to detect a CentOS boot partition using OS Selector. I have researched this in the forums but have not found anything that was of help. There was a thread from someone who had trouble booting Ubuntu on a system with Windows Vista and CentOS but I did not see anything there that looked like it would help in my situation.
Whats the best way to detect & install new hardware in CentOS5.3 when you don't have a working network connection. I've tried to search the wiki & forums on this site as well as the supplied help files for help in detecting & installing new hardware but wasn't able to find anything
I administer a small network of computers connected to a windows 2003 server. The machines Dual boot Windows XP and CentOS 5. My question is this. The machines are being upgraded to HP Z800 workstations. These workstations come with 2 1TB drives setup on a hardware RAID0. Can I install Linux on these machines, using the RAID0? Can I do an install as if it was just one hard drive? The machines came with Windows7 and I'd like to keep it intact including the RAID0. Can I do the install where it resizes the partition, adding the linux partition to the "drive".
If I can't use the existing windows RAID0 to install CentOS I was thinking of just installing another hard drive in the machines for it. This brings up another question, what would happen if I moved my Linux drive from one of the old workstations and put it in the new workstation, would it boot? I know windows wont boot like this because of the hdd controller drivers and I have a sneaky work around for this anyway but am not wanting to transfer the windows installation.
In order to get multiple monitor/display support which is not available in the version of gnome available with centos repos, I decided to try KDE. I tried just adding it with yum without removing gnome. Now I don't seem to get a display after "starting udev (OK)" message during boot. As a newbie I don't know how to go about backing out of this update. is ther some way to boot to a console? Then what would I do - yum uninstall kde? And I suppose I also need advice on what I should be doing to get kde going to support my two monitors.
In my office i have a network of 172.16.31.0 and a squid proxy server running, all other systems have windows XP and one system has centos. On centos system i have three lan cards and i want to test some things on it. So i assigned another IP on it of range 192.168.7.0/24 and same range on another windows system. And all the systems connected through a same network switch.
Unable to ping between Centos and Windows system. If i ping from one centos to windows system with the series of 172.16.31.0 then it replies very well but same thing is not happening in other 192.168.7.0/24 IP series.
The installer can't see my raid controller (I assume) as I'm getting the following error:"Error opening /dev/mapper/isw_jbhgjgjj_Vol0: No such device or address"It just sees them as 4 individual drives: sda, sdb, sdc and sdd.Please note that I have set up the RAID 5 in the controller bios interface and the image name is Vol0, which it seems that it tries to load but for some particular reason it can't.I have also tried different bios settings and nothing worked.
My problem is that I'm trying to install CentOS 5.4 x86_64 DVD ISO on Supermicro X7SBI server with installed Adaptec RAID 3405 controller.
I created RAID 5 array and is working fine (adaptec status says Optimal) but I can't install CentOS to that array (1.5TB size).
Whenever I try to install with: linux dd
I'm asked for a driver, which I have downloaded from Adaptec site and extracted contents to USB drive (in installation found as /sba1) which has now a lot of IMG and some ISO files on it.
I try to load (I simplified names) RHEL5.img, CENTOS.img... with x64 names (one exact name: aacraid driverdisk-CentOS-x86_64.img) and I always get the error message: "No devices of the appropriate type were found on this driver disk"
This is going on for a week now and I can't find the right driver or something I'm doing wrong to get install done.
I am trying to install CentOS-DS on version 5.4 x86_64. I cannot get to the Extras repo due to lack of wired Internet access. I have wireless (except to server) and I have big UFD drives.
I need your help urgently. I will shortly install Centos 5 on a HP DL380R05 E5420 Server with two HP 146GB 10k 2.5 SAS HP SP hard disks running hardware RAID-1. I am a newbie on CentOS, please advise me:
1. Do I need a Centos RAID device driver for hardware RAID-1 on the HP DL380R05 E5420 Server? 2. Should I use Centos i386 or Centos x86_64 in this case? Which one: CentOS 5.2 or CentOS 5.3? 3. Does Centos support Embedded NC373i Multifunction Gigabit network cards?
The following is my server's hardware configuration:
HP DL380R05 E5420 2GB Base AP Server(1) Quad-Core Intel Xeon Processor E5420 Two Embedded NC373i Multifunction Gigabit / 2 GB (2 x 1 GB) PC2-5300 Fully Buffered DIMMs (DDR2-667)/HP Smart Array P400/256MB Controller /Rack (2U)/Hot Plug Fully Redundant Fans Standard Two HP 146GB 10k 2.5 SAS HP SP HDD HP 1000W IEC C14 Cord RPS Kit
I want to install CentOS from netinstall CD, but it doesn't work for wireless connection, because it just looks up for eth0 connection. Well, I connected server to wired USB connection and it's named eth1. I want to use netinstall CD but using eth1 connection. Is there any way for doing it?
I am having new hardware and IDE driver for that hardware as drive disk image (it8213_centos53.img). CentOS 5.3 installation is working fine with drive disk image at USB and CentOS 5.3 at DVD. Our application uses CentOS 5.3 and we build a custom kick-start ISO for installations. Using that ISO client is going to install on all hardware boxes.
Note while installing : a) No network connection is avalible. b) No USB isavalible. c) No floppy is avalible. d) Only single CD-ROM is avalible.
So, is it possible to build single custom kick-start CentOS 5.3 ISO which contains dirve disk image and entire installation will be done using that image. If so please let me know the steps to build it.
I've been trying to install the Fuppes media server onto CentOS and have had a few difficulties. I had to do a build from the source (svn build 578), then configure, make and make install. So far so good.Once I try to run fuppes, I get the error:[ERROR] Failed to bind socket to : 8.15.7.107:0.The documentation I've searched so far suggests that there is a config file that needs to be set with the appropriate ip address, but the file doesn't exist as the program hasn't started up yet!
I'm trying to install CentOS 5.5 on an old Pentium 4 desktop PC I have, which is not being used for much other than being a MTA, and I want to migrate this functionality onto the CentOS platform for stability (Windows is a perpetual nightmare. I partitioned a spare 20GB to experiment with, and I want to install CentOS into here to play around with first so I can move my files around between Windows and CentOS, until I'm happy all of the stuff is gone, then I can scrub the Windows partition and claim the space for CentOS.
So, I've downloaded and burned the DVD and tried to install. I start the install with no args from the main install menu, and the process goes through some probing and then comes up with the "Welcome to CentOS" menu. I go through this, and then it tries to start X Server. It fails, and falls back to text mode. I get the "Welcome to CentOS" screen again, and then proceed through it. I set my keyboard layout to UK, then this message comes up at the bottom of the screen:
"_X11TransSocketINETConnect() can't get address for localhost:6001: Temporary failure in name resolution"
then on the next line: "Cannot open display :1" If I force the install to text, by typing "linux text" at the first menu, I get about the same way through, but the install just hangs doing nothing, and no disc access to the install disc.
initially i was using ubuntu-9.10 and recently i installed centOS. now, i m not able to boot ubuntu, only centOS is getting booted, this is the content of my /boot/grb/grub.conf in centOS:
I had a Centos 5.5 system working great...and then due to crazy curiosity, installed the kernel update. Did this through the graphical interface, uncheck all update other than kernel. It downloaded, installed fine..After reboot now all I get is GRUB_ and then nothing else! I waited 3-4 minutes and had to shut down system. Have been googling around but thought I will post it here as well..When I boot with Win7 and use Ext2fsd to check, the boot folder is empty. Not sure if this is because ext2fsd does not read boot folder or it got wiped out by the yum upgrade process.
I have recently run an update and now we are unable to boot the newer kernel. We get stuck as below;
Memory for crash kernel (0x0 to 0x0) notwithin permissible range Red Hat nash version 5.1.19.6 starting Unable to access resume device (/dev/VolGroup00/LogVol06)
[Code]...
The kernel version we were at was 2.6.18-194.el5 and the update move us to 2.6.18-194.17.1.el5. I've done some googleing but I'm unable to work out exactly what I need to do. I'm guessing the new kernal is missing a module?
1 I have 2 SATA drives - The first (/dev/sda) is a Windows only drive The second (/dev/sdb) has a Linux Partition + Swap (sdb1 and sdb2) of 40GB and the rest is an ntfs partition(sdb3)
I used to have Ubuntu on the Linux partition that nicely detected Windows, installed the bootloader on sda and correctly set up the boot options, everything "Just worked"!
Since I'm studying for RHCT I decided to wipe Ubuntu for CentOS, Centos also nicely detected an "Other" operating system, but it decided to install the bootloader to sdb. After a few minutes of frustration I realised this had happened and changed the BIOS to boot sdb instead of sda. While GRUB now happily boots CentOS, When I select Windows it just hangs.
I tried grub-install /dev/sda and changing the BIOS to boot sda, all I got was GRUB GRUB GRUB printed on the screen and then nothing happens.
get both OSes to boot? I suspect that windows doesn't like it if the bootloader is on a different drive to it's own partition.
UPDATE
It's OK I tried again to grub-install /dev/sda and changed the /boot/grub/device.map file and reversed the hd0 and hd1 entries, i then edited the menu.lst file and did the same, it now boots both OSes ok. The only downside is the nice CentOS background is missing in Grub now :)
I can't be the first one with this problem. What am I missing?
I have setup Samba servers in the past, just none under SELinux. The last one I configured was a couple years ago, so I wouldn't doubt I'm a bit rusty.
---- Environment summary: Clean server install of CentOS 5.4 includes SELinux - lets call this 'server' - updated samba to 3.0.33-3.15.el5_4.1
Client1 - Windows XP sp4 - WINS configuration uses 'server' noted above Client2 - Windows Vista - WINS configuration uses 'server' noted above
---- What works / what doesn't ------ Clients can see the server (XP and vista) in network neighborhood. The following does not work from windows (xp or vista) net view net view \server net view \server-ip net view \servershare
This does work on the server smbclient -L \server smbclient -L \server --user validuser smbclient -L \client1 --user validuser
---- What I have configured and tried (config/output below) -------- firewall ports for samba are open SELinux enforcing or permissive file context is set on share samba booleans are set

I have an i5 Thinkpad running Windows 7 64-bit. VT is enabled in the BIOS. I have installed vmware server v 2.0.2 but am unable to install Centos 5.5 x86_64 as a guest OS. The steps that I followed are as follows:1. Created a new VM, specifying RHEL 5 64-bit as the intended guest OS (per vmware documentation - Centos is not available as a selection2. Downloaded all 8 iso files for Centos v5.5 64-bit3. Modified the CD/DVD drive to 'connect at power' and use an iso with the path pointing to the x86_64 iso 1 of 8When I power up the VM, the console window displays 'ISOLINUX 3.11 2005-09-02 Copyright (C) 1994-2005 H. Peter Anvin' and nothing else. The installation splash screen never appears. As a test, I downloaded the first of 7 iso files for the 32-bit version of Centos 5.5 and pointed the CD/DVD drive to that iso. In that case, the installation starts as expected. I would really like to get the 64-bit version installed and running.
i am not able to port 8080 on my CentOS VPS server.I have followed all the instuctions as mentioned on iptables wiki page.Also I am able to telnet my ip address and port number, But can not access from browser.
I have two Centos 5 servers one running Asterisk with PHP installed and another sever running as a MySql Database server, at the moment when I try run simple script to see if I can connect to the remote server I get the following error.Quote:Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
I recently added a new graphics card to my machine. Normally, Centos 5.3 runs without a hitch, but since the new card, boots as far as a kernel panic. Even a rescue or an install disk comes up with a kernel panic.I have tried Centos and Fedora CDs/DVDs.The card is a PCIE Radeon HD 4350.It works fine with XP, btw.Ubuntu and OpenSuse will load from install sources.
I've noticed this happen with every CentOS installation I've done in the past and it's confusing me. On the software template screen select, I always select "Server" and leave the extras option unchecked, I also check "Customise now". The only things I choose are the editors (to get vi), Web server and server configuration tools (and this time also Java). I didn't select any GUI programs, yet it still installs things like X, GNOME components and also samba. Why does it do that? There no way they're needed for dependencies. Is there something I'm missing when selecting the software components? Why does it still install samba when I didn't select it from under "Servers" components? Or have I misunderstood what software selection does and it installs all those components regardless but doesn't automatically turn the services on?
I have Windows XP installed. And I also plan to install CentOS 5.4.I have two hard drives. Hitachi 500 GB and WD 500 GB.Windows XP is intalled on first drive And I plan to install Linux on Second drive. And since i find some contradicting and not understood by me posts. I have to be sure what to do. I can install Linux, then i can edit grub. and add there something like:
title Windows map (hd0) (hd1) map (hd1) (hd0) root (hd1,0) chainloader +1
When its on one drive as I understand it will definately work. But if its on 2 different drives. There is a problem that windows doesn't boot from secondary drive. So I find this article witch i cannot understand. Do i have to understand it? Or its wrong and bad decision.

I have no RAID.After all what is step by step process of creating bootable CentOS and Windows situated on different hard drives drives?
So far, I've been able to get my Box (Centos 5.3) authenticate users through LDAP. My next plan was to automount their home directory from our NAS device.But I'm struggling getting autofs talking to the LDAP Server.My Config Files:
