A bit of LQ advice: thread titles such as "Urgent" are frowned on here. Something descriptive, maybe like "CentOS install went awry need to recreate overwritten partitions" would be better. You can change the title using the thread tools.

If the headphone jack does not work under two different distros, it may well be a hardware problem. Alternatively, if it worked under Windows, it might be a driver issue with the sound card. The command lspci in a terminal should report the sound card so that you can look into the driver issue.

My suggestion for restoring would be to restore the Windows first, then use GPartED top create partitions to receive the Linux images, but that's strictly from what I've picked up here--Others can likely deal with that more effectively. I don't know how a grub install would work from an image restore--that's something that would require some research.

If you don't have any significant data in either of the Linux images, it might just be easier to install them afresh.

I'm glad you're up, running, and happy, but I thought this question deserved an answer.

Since you don't want to use Windows any more, there was no reason to install it. My advice was based on this: If you install Windows after installing something else, such as a Linux distro, Windows will trash your bootloader. Installing Windows first avoids the hassle of recreating/repairing the Linux bootloader.

I don't think it's so much that Windows is malicious; rather, it's self-centered and can't conceive of the possibility that a computer can have any other purpose in life than running Windows.

Thanks again frankie.....

I have posted.another query can you please advise ? n that

I'll be happy to display my ignorance (grin).

Link?

Hi guys / frankie


I have successfully installed,ubuntu 12.04 LTS. I is awesome.

I have now 4 partitions

1. 25gb for ubuntu + 5gb swap ( already up and running)
2. 30 gb i have set aside for centos it is in FAT32
3. 30 GB for opensolaris also in FAT32
4. Rest for storing my files.

How can i install centos and opensolaris without damaging existing ubuntu?
I have to use usb boot loader cd driver aint wrkng.

Ubuntu resolved my headfone jack not wrking issue.... :-)

Please advise....

When you do the install, pick the appropriate empty partition for the OS you are installing.

My inclination would be not to let the new installations install their bootloaders, but to add them to the existing bootloader after the install is completed.

But I'm not the best person for this, because I've only done one dual boot system, which led to its own thread here on LQ. http://www.linuxquestions.org/questi...s-grub-874480/

This might help: http://www.dedoimedo.com/computers/grub-2.html

I said I would be displaying my ignorance (grin)!

Taanx a lot frankie........!!!

Lemme giv it a shot.. I ill post d result....!!

Be aware that these will only work if you let them re-format to their native FS formats, not FAT32.

Hi Chris,

Can you please advise on the bootloader issue that may happen if i install CentOS? lets set aside Opensolaris.

I have a ready to install CentOS bootable USB drive.

But am a lil hestitant to install it, as i lost all my data previously trying.

I have a confusion going on, if i install CentOS in that 30GB partition, (which i ill reformat when i install CentOS to ext2) will there be any conflict between the bootloader of Ubuntu (my present primary OS) and the new bootloader of CentOS in GRUB?

if so how can i resolve? If a conflict occurs to which OS will i be able to log in to, CentOS of Ubuntu?

If i have to edit GRUB conf, how can i do that? Can you please advise. I havent edited GRUB conf before so little tentative.

Please advise,
Sriram A Das

Since you are using Ubuntu, I recommend the Ubuntu article on Grub for your research.

https://help.ubuntu.com/community/Grub2

This article might help: http://www.centos.org/modules/newbb/...30639&forum=37

My initial feeling is not to allow CentOS to install its bootloader or at least put it on the CentOS partition, not in the MBR (if the installer allows those options--it's been over a year since I last installed CentOS).

Then let grub-update (see the first link) add CentOS to the Ubuntu bootloader. I'm just talking off the top of my head here from the little bit I know. Hopefully more knowledgeable persons will correct me if I'm wrong.

Have you considered installing CentOS in Ubuntu in a virtual machine? I looked up the specs of that machine and it has plenty of juice for doing that.

If you do have more questions before trying this, it would likely be a good idea to start a new thread with the appropriate title to give it maximum visibility.

Hi Frankie,

I have been using CentOS, Opensolaris in Virtualbox installed in Ubuntu 11.04 for a while now.. The thing is CentOS installation with in a virtual machine is always hangingup.. and i have to reboot the whole system to get back the speed..

So i thought of giving it a formal space in my HDD rather than living with in Ubuntu.. and i can have a faster machine also..

I will give the links u gave a shot,.. lets c what happens..!

Thanks,
