Version: 1.58 Hello,
I never had this error before using the kernel from wheezy-backports, but now apt said that there are these updates available: linux-compiler-gcc-4.6-x86 linux-headers-3.16.0-0.bpo.4-amd64 linux-headers-3.16.0-0.bpo.4-common linux-image-3.16.0-0.bpo.4-amd64 I installed them and it called update-grub as expected. Before the updates update-grub correctly detected all 4 operating systems on my computer and I could start them all without problems. But now I experienced just the same error and it only detected the current running OS, Debian Wheezy, and Windows 8. After mounting the other two partitions manually everything works. The versions that the packages were updated to: # aptitude versions linux-compiler-gcc-4.6-x86 linux-headers-3.16.0-0.bpo.4-amd64 linux-headers-3.16.0-0.bpo.4-common linux-image-3.16.0-0.bpo.4-amd64 Paket linux-compiler-gcc-4.6-x86: i A 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-compiler-gcc-4.6-x86:i386: p 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-headers-3.16.0-0.bpo.4-amd64: i 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-headers-3.16.0-0.bpo.4-amd64:i386: p 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-headers-3.16.0-0.bpo.4-common: i A 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-headers-3.16.0-0.bpo.4-common:i386: p 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-image-3.16.0-0.bpo.4-amd64: i A 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-image-3.16.0-0.bpo.4-amd64-dbg: p 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 Paket linux-image-3.16.0-0.bpo.4-amd64:i386: p 3.16.7-ckt4-3~bpo70+1 wheezy-backports 800 The versions of the responsible packages: # aptitude versions grub2-common os-prober Paket grub2-common: i A 1.99-27+deb7u2 stable 900 p A 2.02~beta2-21 unstable 10 Paket grub2-common:i386: p 1.99-27+deb7u2 stable 900 p 2.02~beta2-21 unstable 10 Paket os-prober: i A 1.58 stable 900 p A 1.65 unstable 10 Paket os-prober:i386: p 1.58 stable 900 p 1.65 unstable 10
