Hi

I've grub as bootloader booting 3 Linux OS including Vector. Able to load other 2 Linux fine, however Vector doesn't work. Keeps throwing root partition is not enabled for write, VFS syncing, (don't remember exact error messages and their sequence).

Disk partitions look like this -

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        7056    56670208   83  Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2            7057       11087    32371889+   5  Extended
Partition 2 does not end on cylinder boundary.
/dev/sda3           11088       12161     8626905   83  Linux  (VECTOR IS INSTALLED HERE)
/dev/sda5            7057        7504     3590968+  82  Linux swap / Solaris
/dev/sda6            7504       10691    25605688+  83  Linux
/dev/sda7           10691       11087     3175168+  82  Linux swap / Solaris

and grub looks like this -

title Vector
kernel (hd0,2)/boot/vmlinuz root=/dev/hda3 resume=/dev/sda7 vga=791
initrd (hd0,2)/boot/initrd

Can anyone please guide me in pointing the issue why Vector isn't booting properly.

For troubleshooting, I would make the GRUB entry as simple as possible:

title Vector
kernel (hd0,2)/boot/vmlinuz root=/dev/hda3 ro vga=normal

You can also try booting VL using the install CD. There is a point where it asks you to press Enter to continue, or type in the path to your installation. Modify the example to fit your system. If it boots okay that way you know the install is good.

Tried everything as per your suggestion but nothing seem to work. Tried the boot from hard disk as well with live usb but it complained about partition being rw, it has to be read-only. Then i changed to read-only when it started complaining about Kernel panic and VFS syncing error. Kind of catch-22 situation here. Not sure if it is an installation issue or something else. Maybe i'll try downloading v6.0 and see if that goes through ok.

For the USB boot, try the following:

linux root=/dev/sdXX ro rootdelay=10


Change sdXX to the USB device you have defined on your system. This may allow the system to boot up the USB device and allow you to view the partitions on your hard drive.

USB boot is not an issue, that goes well. I was trying the boot from hard disk using advanced boot options when the live usb is plugged in.

What is the exact panic error that you receive?

Don't remember exactly but something about "Root partition cannot be read only, this is a serious error. VFS Syncing" Since it didn't give me terminal prompt or anything i was forced to do hard reboot and didn't write down the error message which was about a full screen.

You may need to use "/dev/sda3" instead of "/dev/hda3".

Try booting VL using the install CD and see if the installation is good. You posted something about trying VL6... if you are still using a 5.x series, I would highly recommend upgrading to a newer version.

Yes, I did install VL6 and didnt had much issues w.r.t Grub until i uninstalled one pkg and it borked my system. Was little surprised since it didnt list out what all would be removed but finally i had a completely dead system. Was quite disappointed, will reinstall again over the weekend..

Do not remove via gslapt. Not only will it remove the package, but every single dependency associated with it. If you want to remove a program, use removepkg in terminal.
