It is confirm after 6 times of grub-install with the error "Sector 50 is already in use by FlexNet",
1. you can successfully reinstall grub only if you use - usb live cd ubuntu or other installed ubuntu partitions. with exact the same messages as No.2 ------------------------ /usr/sbin/grub-setup: warn: Sector 50 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track. Installation finished. No error reported. ==================== 2. grub-install will destroy "grub boot menu" and you will get "grub command prompt", if you use the command grub-install in the following ways you boot into "current partition", in my case sda4 contain ubuntu 11.04 (I also test with the same result in Lubuntu 11.10) sudo mount /dev/sda(current partition) /mnt in my case sudo mount /dev/sda4 /mnt sudo grub-install --boot-directory=/mnt/boot /dev/sda in my case I want to reinstall grub to sda4 so when the computer boot up it will auto boot into sda4, which is the ubuntu partition I am using to execute the grub-install command. It will produce this message. --------------------------------- /usr/sbin/grub-setup: warn: Sector 50 is already in use by FlexNet; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track. Installation finished. No error reported. ==================== you will get grub> and not your grub menu any longer. I don't know "if I should post this as new bug or not". ======================================== But certainly it is not correct when grub report "No error reported". And you will get a "destroyed grub menu" after reboot. note== the reasons I start to do grub-install from Lubuntu 11.10 to force grub to start Lubuntu 11.10 as default os. because the "startup-manager" fail to change grub menu as it did for previous version. which I don't know why, bugs or just incompatible grub version in sda. But the above "bugs" I have tested and found to be on both Ubuntu 10.04 and Lubuntu 11.10 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/730225 Title: grub-install trashes the ntfs partition that starts at sector 63 if one or more sectors in the embedding area is occupied by Adobe FlexNet To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/730225/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
