Adding windows 10 grub entry (Invalid symlink)

ruyj · 2018-02-18 11:36:49

Hi, I am new to this forum, portuguese, 23y, student, installed arch this week, asus rog gl552vw.
Have 2 disks. one with arch and one with windows.
Trying to add windows one to grub (bios stopped reccon him)

this is my entry after following grub docs

cat /etc/grub.d/40_custom 
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries.  Simply type the
# menu entries you want to add after this comment.  Be careful not to change
# the 'exec tail' line above.
if [ "${grub_platform}" == "efi" ]; then
	menuentry "Microsoft Windows 10 UEFI-GPT" {
		insmod part_gpt
		insmod fat
		insmod search_fs_uuid
		insmod chain
		search --fs-uuid --set=root --hint-ieee1275='ieee1275//disk@0,gpt3' --hint-bios=hd0,gpt3 --hint-efi=hd0,gpt3 --hint-baremetal=ahci0,gpt3 5002647202645ECA
		chainloader /Windows/Boot/EFI/bootmgfw.efi
	}
fi

when i select windows 10 in grub boot menu it says error symlink invalid
"error: symlink type invalid (80000017)"
i can only boot into arch
I am not finding information about this error and i must use windows in short time, hence my post to get some help.
thank you in advance.

--hint-ieee1275='ieee1275//disk@0,gpt3'
chainloader /Windows/Boot/EFI/bootmgfw.efi

I think both of these are incorrect, where did you get them from?

I didnt find that path on my partitions
I guess its sda3 i have to mount, because there is the windows folder there and the programs system etc

inside the only logic path to boot i found it was the one i used
this is ls of sda3

as you can see there is no EFI folder here

/dev/sdb1      2048   1128447   1126400  550M EFI System

What is in the the ESP directory of the partition which is designated as the ESP?

That is the partition i created for arch to boot

cat /proc/mounts | grep sdb1
/dev/sdb1 /boot/efi vfat rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

That is the only ESP from the the output of fdisk -l you posted if there is no EFI/Microsoft/ directory present then windows can not boot from that ESP.
If windows could not use the only ESP present then was there another ESP that was removed or was sda converted from MBR to GPT?

Please make more of an effort to help yourself.

@jasonwryan that will work if there is the windows EFI is present on the ESP. If ruyj wiped a previous ESP or convert sda from MBR to GPT then it would probably need some windows tool to repair the issue.
However without ruyi stating or showing what is on the ESP I can only speculate.

If that is the case, it is offtopic here anyway.

Well after reading more about this, one of the partitions is the mbr windows, the one with 16mb.
i never had efi on windows
i am trying to find a safe way to make efi partition for the existing windows, i dont want to fix the mbr, because it conflicts with grub
