Privacy Terms. Quick links. I made a bunch of mistakes mostly fueled by ignorance, anyway as a possible help to others out there stumbling around in the dark, perhaps my notes here will help flip on the light-switch and make this process easier for someone else.
Since Centos7. Prior to this I had used my CentOS install disk's recovery mode to give me a shell where I could use "gdisk" to make the 1Tb disk use a gpt partition table as opposed to DOS.
It's possible if you start with a DOS partition table that the Windows 10 installer will flip it for you, but I had already in my many failed trials apparently tried to install non-UEFI Windows 10 onto a gpt partition tabled disk and it simply refused to deal with it I think I did so many variations that it's hard to recall all the road blocks.
So, proceed with the Windows install - it will take over the whole disk. Once it's all installed free up some space with "Shrink" via the disk management tools lots of help to do this online.
Once this is done, reboot, and with the same proceedure, launch your CentOS 7. The following link is really useful especially IF you do the above steps because then the instructions on the web-page will mirror what you see on your screen - otherwise, it's going to be different, and different is BAD. I'm fuzzy on the whole Good-Bad thing, OK, Imagine every molecule in your body simultaneously exploding at the speed of light Nothing else should need to be done!
I hope that helps - It will probably help me again in a year when I completely forget this entire process. Cheers, James. Last edited by jimbux on Wed Oct 18, pm, edited 2 times in total. I did an update to Windows last night that perhaps stomped on something important this was first time booting since successful installs followed by win-update last night? I don't know. Wow - this process is so difficult. Last edited by jimbux on Thu Oct 12, pm, edited 2 times in total. I found something that seems to be on the right track, from Ubuntu forums.
Does anyone know the CentoOS equivalent to this? So the next time windows wipes the efi - you can easily restore. I was still able to dual boot both win10 and CentOS 7. Thx for the suggestions, but I don't think VM is for me. I use some memory intensive applications and want to minimize the footprint of the OS. Also, my gut tells me that running one OS inside another may have it's own set of issues that I'd prefer to not layer on top of the usual host of difficulties when faced with debugging something that isn't working right.
Perhaps I'm wrong and using a VM is smooth as silk and no different than what I'm doing, but I doubt it. So why UEFI? Good question. I believe that was limiting how many partitions could be made on the disk, so when I installed CentOS it ended up stomping on some Windows partitions and consequently win10 became unrecoverable and couldn't be repaired thus my repeated adnauseum number of reinstalls - I had my windows key memorized that's how many times I did it.
When I reformatted the disk to be gpt - using gdisk or fdisk the Windows installer would NOT let me install win10 - and apparently it's because I was still trying to install it in non-UEFI mode.
Thanks again to everyone who pitched in ideas to help me out! I downloaded the everything version I guess and I created a bootable usb using rufus.
So I went through the process and it is even asking me to create 1 MB of partition for biosboot and I did. So it went through the install and as I enter the root password, the installation froze. I reset the laptop and now, it won't boot my windows First, how to properly install centos on a laptop?
Is rufus a recommended tool to use? Optional, if you can tell me how to fix windows boot record that would be awesome. Thank you in advance. Board index All times are UTC.
