Windows 10: Help! Laptop stuck in bootloop after CentOS installation attempt

I installed CentOS on a 64GB flash drive. I went to BIOS and tried to boot off the drive but it didn't work. I gave up, took out the flash drive and went into Windows.

I shutdown my laptop (in Windows) and I noticed it turned on again. I checked my BIOS settings and everything seems to be right. No matter what I do, it keeps turning on after I shut it down.

I took it off A/C power and am running it on battery now.

Help!

Can not detect windows 10 after installing centos 7

Hi Sachin,

Thank you for valuable response.

• What is the make and model of your system?

I have no idea how to see that, & since i have only centos 7, it is not easy to find solution on it despite looking for google. Please let me know how to see that?..

still what i know is :

-Laptop model: Sony SVF15218

-Processor : Intel Core i5-3337U CPU @ 1.80 GHz x 4

-OS type : 64-bit OS(Both Centos 7 & Win 10)

-Graphics : Intel Ivybrigde Mobile & NVIDIA GT740M

-HDD : 500 GB

-RAM : 4 GB

• Since when are you using the dual boot?

-I had windows 10 as as a single for almost 2 years. For study purpose i had to install linux (near suited to Red hate), i choose Centos 7 as it is free.

-I installed Centos 7 on 2nd January 2016.

-At that time i get help from google & successfully dual-boot as windows 10 shows as windows boot manager & centos. (I can switch between them any time from grub menu.)

- Due to lack of wifi adapter in centos, while installing packages something went wrong & i had very limited access to centos, so reinstalled centos 7 around 15 days after successful dual-boot(18th Jan) (performed same steps to install as i did the first
time) & since then my in the grub menu i can only see centos.

-I tried install centos 7 2-3 time after tha to see windows in grub menu, & i testes/altered almost everything in centos but found out that my windows is somehow not detected by grub.

• Did you check in msconfig regarding the boot menus, are you getting both the Windows and Linux Boot loader menus?

- Since i am using linux i have no idea how to do in windows.

- But i played with centos's grub menu lot of time since missing windows bot manager in grub i am (99%) sure that there is something wrong with windows grub detection.

Hope i find solution soon...

Thank you...

 

Can not detect windows 10 after installing centos 7

Sorry for the late reply as i am currently working on centos 7, i do not wish that it gets lost during windows recovery process.

• How many drives are you able to see in the Linux explorer?

Yes, i can see 2 windows hard-disk partition c - 146 GB, :d -150GB) from linux & i can access both of them at any moment from linux.

• Do you have Windows 10 installation disc with you?

I do not windows 8/8.1/10 dvd, but i backup dvd as 3 dvd that can restore my windows 8 (officially came when i purchased sony laptop) as when i want, bu the problem it takes 5-6 hours to install & since it will master reset my harddisk every-time i do. Doing
so will definately remove my cent os.

The further problem is when win 8 it upgrade to 8.1, it will again reset grub menu & so does from 8.1 to 10. So, every-time i might/will have to repeat installation of either os. & that i definately do not want.

I hope this steps will not remove my current working os centos 7 in the process.

I will update here once i do the steps.
