You can check this by loading the UEFI boot menu and trying to load the "Windows boot manager" entry. Then I managed to add it to grub using grub2-mkconfig,.
All went well except Windows is not on the boot list in grub. I've tried everything I could find. Very frustrated. So here's what I have. I sure hope someone can help. Reboot the system. Run the command again. Anyone Help with this to resolve this error. The boot loader gets installed to the already existing EFI partition, so choose this one Thank You for your great idea it works well and I also found another option as running in legacy mode detects the EFI partition automatically So the installation goes smoothly.

Hi Venkat, This is most probably due to the fact that all partitions on the disk are formatted with ntfs. I've made a presentation to make it a bit easier to understand : How to prepare a GPT based disk for an installation of a Linux operating system with GParted Once finished, boot from the RHEL installation media and select the option "I will configure partitioning" from the Anaconda installer.
Cheers : Christian. Hi Venkat, It seems that you've chosen the default option when you installed RHEL, which can mean that the whole disk was wiped Regards, Christian. Installing Red Hat I installed Red Hat next, using the partitions I had already created using the previous aborted install. At the boot loader screen, I added the Lindows entry by hand, and pointed it to the partition containing Lindows.
While Red Hat installer can detect a previously installed Windows OS, it cannot detect a partition with another Linux distro installed. So, this label was not automatically provided on the boot options screen. Red Hat installed fine. But when I tried to boot up Lindows, the kernel was not found. So, I went back to Red Hat, and edited grub.
This is how my final grub. Surprise Well, everything was going fine, except when I rebooted the system it came back up with the Lindows splash screen, instead of the GRUB screen! And of course, there was no option to boot up to Red Hat anymore. So, while Lindows was booting up, it changed the boot loader configuration without asking!
Later I found out that the system has a program called "fooze", which automatically changes lilo. Apparently this program is descendent from Corel Linux. Supposedly this fooze program, does not update the lilo. Lindows did not install either "man" or "info"!!!! You can install man pages by going through the "Click-N-Run Warehouse".
I could have just gone through with the Red Hat install during the first step when I used Red Hat installer to just partition the disk. Editing lilo. So, I created the lilo entries based on this location of the Linux kernel and initrd files for Red Hat. Note that you cannot use the paths as they appear while system is booted up with Red Hat e.

A Windows installed on the bare metal won't work in a VM and vice versa.
Once loaded, the Disk Management tool will display a graphical representation of the disk drives detected on the system:. Right-click on the partition you wish to reduce in size and select Shrink Volume The tool will calculate the maximum amount by which the volume size can be reduced without data loss a process that can take several minutes depending on the overall size of the partition.
Once this analysis is complete, a dialog similar to the one in Figure below will appear:. Enter the new target size for the partition into the Total size after shrink in MB field and click on the Shrink button to proceed. At this point, the boot menu only provides the option to boot the RHEL 8 system. Clearly an option also needs to be added so that the Windows system is still accessible. These steps will need to be taken from within the RHEL 8 system, so start the system and log in as root.
