I did what the Documentation for Multibooting said and added Stanzas for Windows and Linux Mint to Grub 2 to /etc/grub.d/40_custom after installing Qubes.
My Partitions are the following: *sda1 "DellUtility" vfat* *sda2 "RECOVERY" ntfs* *sda3 "OS" ntfs* *sda4 extended* *sda7 Qubes ext4* *sda8 Qubes crypto_LUKS* *sda5 Linux Mint Swap * *sda6 Linux Mint ext4* My /etc/grub.d/40_custom looks like this after adding the stanzas: *#!/bin/sh* *exec tail -n +3 $0####* *menuentry "Linux Mint 18" {* *set root=(hd0,5)* *chainloader +1* *}* *menuentry "Winodws 7" {* *insmod part_msdos* *insmod ntldr* *insmod ntfs* *ntldr (hd0,2)/bootmgr* *}* I've tried out all possible partitions for root=() and ntldr () but the Linux always gives me "error: Invalid Signature. Press any key to continue." Did I do any mistake while editing the 40_custom file? For Windows I get something like *"Windows failed to start. A recent hardware or software change might be the cause. To fix this problem:* *1. Insert your Windows installation disk* *2. Choose language* *3. Click repair your computer* *file: \boot\BCD* *Status: 0xc0000225* *Info: An error occurred while attempting to read the boot configuration data."* Is that really necessary (I don't have such a disk)? There should not have been made any changes to the Windows Partition so I do not understand why it won't boot... I really appreciate any ideas on how to fix this issue. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
