[SOLVED]GRUB does not load windows

I have installed arch on a disk, latter I have added another hard drive with windows. Now I am trying to boot windows with grub. I have followed wiki and I have already tried changing /etc/grub.d/40_custom by following this

According to wiki I should mount windows containing partition.

 sudo mount -t ntfs-3g /dev/sda2 /mnt/windows 

Then I entered command to detect other systems.

 sudo os-probe 

There was no output, if in any case there should be I am mentioning it.

lsblk output:

sda      8:0    0 465.8G  0 disk 
├─sda1   8:1    0   100M  0 part 
└─sda2   8:2    0 465.7G  0 part 
sdb      8:16   0   477G  0 disk 
├─sdb1   8:17   0 472.5G  0 part /
├─sdb2   8:18   0     4G  0 part 
└─sdb3   8:19   0 449.3M  0 part 

sda is disk with installed windows and sdb is disk with installed arch.

Re: [SOLVED]GRUB does not load windows

Could you verify if the disk UUID for your Windows partition is the same as what you have in your 40_custom?

Re: [SOLVED]GRUB does not load windows

sudo blkid /dev/sda2
/dev/sda2: UUID="525CEAB95CEA96CF" TYPE="ntfs" PARTUUID="a63ff30f-02"

cat /etc/grub.d/40_custom 
#!/bin/sh
menuentry "Windows 7" {  
     insmod ntfs  
     set root='(hd0,1)'  
     search --no-floppy --fs-uuid --set 525CEAB95CEA96CF
     chainloader +1 
}

I should also mention that in grub "windows 7" option is shown, but when I select it error occures, EFI path not found.

Re: [SOLVED]GRUB does not load windows

Have you installed Arch in UEFI mode? Looks like Windows is non-UEFI so it can't be chainloaded from a UEFI bootloader.

Re: [SOLVED]GRUB does not load windows

Yes, I have installed arch in UEFI mode and windows not. I will mark this thread as solved.
