Dual boot Windows 10 and CentOS 7
Hi All,
I am having trouble Dual booting Windows 10 and CentOS 7 on a UEFI machine: /boot/efi/EFI/centos/grub.cfg. I get two errors. 1. error: not an assignment 2. error: Invalid EFI file path. I don't' know if this has to do with my installation itself of CentOS 7 or my partition scheme. My Windows 10 partition is /dev/sda4. I have edited my /etc/grub.d/40_custom file as follows: menuentry "WIndows 10" { set root = (hd0,4) } Then I ran grub2-mkcofnig -o /boot/efi/EFI/centos/grub.cfg I don't know what else to do. Thanks, kwa71 |
To chainload windows in efi system the entry has to be something like this
Code:
insmod part_gpt |
I have Centos7 dual-booting with Windows 10 in secure boot mode on a Dell machine. I didn't have to edit or mess with any config files. The installation steps I used:
* Log in to windows, use disk management to shrink the existing ntfs windows partition, leaving the new free space unallocated. * Boot the centos usb installation media in UEFI mode. * Install centos7 * Reboot and choose centos from the grub menu (or windows, both choices are present). The only problem I have is I have to sit and watch windows updates so I can catch the reboots and choose to boot windows instead of the default centos. But if you miss an auto reboot, next time you boot into windows the updates will complete. |

I am aware of this, but for myself I don't want to change the default OS, after a power outage or whatever I want CentOS to be running on the machine. Tweaking the default startup is surely an option, but I know there would be the one time I forgot to change back to centos, I'd be out of my office, the juice would go out and none of my centos services would be available until I got back home. Of course, not dual-booting would also work, but the W10 came with the computer, I occasionally use it, and don't want to just erase W10. :) |

Dual Boot Windows 10 and Centos 7
Hi All,
I can't boot into Windows 10 at all. I already have my partition scheme set as Windows 10 /dev/sda4. insmod part_gpt what is this part_gpt for insmod? insmod fat Is there an ntfs for insmod? set root='hd0,gpt1' chainloader /EFI/Microsoft/Boot/bootmgfw.efi I also don't have a Microsoft efi file to add to the chainloader argument. Please forgive me for saying so but this doesn't seem like it's Centos 7 specific. Please explain Thanks, kwa71 |
