Hello,

I recently bought the Acer Aspire V3-551G-X419 Laptop. It came pre-installed with Windows 8. I wanted to install Fedora 19 on it so i used Gparted live cd to resize my HDD and installed Fedora.

Now i'm unable to boot into windows though i can see all the files (from windows) if i mount the partition. Fedora works fine. I went trough the questions asked by multiple people in this site and tried out their solutions but it did not work for some reason.

Here is the output when i tried the blkid command -

[root@localhost ~]# blkid

Please help!

Also this is what i got when i tried the parted /dev/sda command -

Here the 4th partition has my windows 8 installed on it.

I did all the steps except - grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg this shows the error "No such file or directory". What path should i entering here? The path to the grub.cfg file? For me it would be /boot/grub2/grub.cfg - is this what i should be entering?

tdl.ver713 ( 2013-09-20 05:55:16 +0000 )edit

mount /dev/sda2 /boot/efi and try again the same command if it still return error try with grub2-mkconfig -o /boot/grub2/grub.cfg

Didn't work, it did create the grub.cfg file but it contains entries only for Fedora. Windows does not show up.

As you have UEFI setup for windows 8 .you have to search where your windows 8 bootmgr files stored . then disable Grub2 OS prober echo GRUB_DISABLE_OS_PROBER=true >> /etc/default/grub

Establish the EFI boot partition holding the Windows boot manager and probe it for string hints search parameter (in my case it was: "/efi/Boot/bootx64.efi". I found lots of examples pointing to "/boot/efi/EFI/Microsoft/Boot/bootmgfw.efi". Note that, in fedora, the command for this is grub2-probe. Many examples online had grub-probe. This was confusing at first.

grub2-probe --target=hints_string /efi/Boot/bootx64.efi

or

grub2-probe --target=hints_string /efi/EFI/Microsoft/Boot/bootmgfw.efi

here your output will be 06C1-0984 as it is UUID of your EFI System Partition Create a custom menuentry for Win-8 UEFI-GPT system in "/etc/grub.d/40_custom" and add the results of the above command on the search line. It will look like the following:

menuentry "Microsoft Windows x86_64 UEFI-GPT" {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --fs-uuid --no-floppy --set=root 06C1-0984
chainloader /efi/Boot/bootx64.efi
}

or

menuentry "Microsoft Windows x86_64 UEFI-GPT" {
insmod part_gpt
insmod fat
insmod search_fs_uuid
insmod chain
search --fs-uuid --no-floppy --set=root 06C1-0984
chainloader /efi/EFI/Microsoft/Boot/bootmgfw.efi
}

and then enter
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
