Finding lost installation of Redhat


Hello, on my PC I have a dual-boot of Redhat Linux and Windows 8. I recently upgraded my version of Windows 8 and ran into a problem. It now longer gives the option to choose which OS to use at start up. It just goes straight to Windows 8. Does anyone know how I can fix this so I can boot into Redhat? It still shows the Redhat partition under disk management. Do I have to reinstall Redhat? I'll wait for your replies. Thanks

You only have to reinstall the boot loader, not the entire distribution. You should be able to do that using the installation CD/DVD.

This might help:

i take it you did not read nor heed any of the warnings about upgrading windows

the very BEST possible of the bad situation is windows replaced grub as the bootloader
it can not see read nor boot RHEL partitions and can not boot RHEL


use the RHEL 6.5 install dvd and reinstall grub
( see the redhat install guide on the redhat documentation page
https://access.redhat.com/site/docum...erprise_Linux/

or search the redhat knowlage base
https://access.redhat.com/search/bro...#?&language=en
login with your redhat credentials from the REQUIRED support contract you DID buy
-- the support contract IS REQUIRED !!! and you need to buy a new one EVERY YEAR
and reinstall GRUB


or


the WORST thing happened

the 8 upgrade REPLACED ALL OF RHEL

and there is no longer a redhat install on the machine
( i hope you do have a back up of any needed data on the redhat partitions )

windows can overwrite a linux install and replace it win windows

there is a reason that Microsoft Windows is often compared the the star-trek "Borg"

Stop the horror stories. While it is possible that Windows replaces the boot-loader it will not in any case alter the partitioning of the disk or randomly overwrite partitions, otherwise it would be useless for Enterprise use, something that Microsoft won't risk.

If I remember right, that only happened during a fresh install of windows. It always overwrote the boot sectors though.

Even that is depending on which DVD image is used for installing. Most OEM versions do indeed repartition the harddisk when they are used for installing, the Systembuilder, Corporate and Retail editions always involve a manual partitioning step.

Hello, thanks for the replies. Sorry it took me awhile to get back, but I solved the problem. I put the original disk in and clicked install and it re-installed the boot loader. So it didn't take long, I just needed the boot stuff and now i'm fine. Thanks
