I cannot boot the operating system on my laptop. I have three versions of the kernel installed and none of them will boot.Booting into Windows (installed in a separate partition) still works, so I suspect the hardware is not at fault. I may have tried to update drivers before the problem occurred, so that could be the cause. I have also tried resetting the BIOS, to no effect.I am using GRUB v1.99.Selecting Fedora (3.6.11-1.fc16.x86_64) from the GRUB menu, the following is displayed:Fedora (3.6.11-1.fc16.x86_64)Loading initial ramdisk ...Then I get the normal splash screen. But then it returns to the black screen with just the above two lines being displayed and hangs indefinitely.Enabling verbose mode yields the following:Fedora (3.6.11-1.fc16.x86_64)Loading initial ramdisk ...... (many lines - can transcribe if relevant) ...Started Machine Check Exception Logging Daemon             [OK]Started Install ABRT coredump hoot                         [OK]Started Console Mouse manager                              [OK]Started irqbalance daemon                                  [OK]Started SSH server keys generation                         [OK]Started Kernel Samepage Merging                            [OK]Started Harvest vmcores for ABRT                           [OK]Started ACPI Event Daemon                                  [OK]Started Display Manager                                    [OK]_(hangs here)No obvious errors are displayed - it just stops.The grub config looks like:setparams 'Fedora (3.6.11-1.fc16.x86_64)'load_videoset gfxpayload=keepinsmod gzioinsmod part_msdosinsmod ext2set root='(hd0,msdos2)'search --no-floppy --fs-uuid --set=root dd61afbf-2b76-44ab-b2ca-0e65f0664425echo 'Loading Fedora (3.6.11-1.fc16.x86_64)'linux /boot/vmlinuz-3.6.11-1.fc16.x86_64 root=UUID=dd61afbf-2b76-44ab-b2ca-0e65f0664425 ro rd.md=0 rd.lvm=0 rd.dm=0 quiet SYSFONT=latarcyrhebsun16 rhgb KEYTABLE=uk rd.luks=0 LANG=en_US.UTF-8echo 'Loading initial ramdisk ...'initrd /boot/initramfs-3.6.11-1.fc16.x86_64.img/boot is in /dev/sda2; using a livedisk to inspect the directory yields the following:cd /mnt/sda2/bootls -ld *-rw-r--r--. 1 root root   119880 2012-08-15 17:01 config-3.4.9-1.fc16.x86_64-rw-r--r--. 1 root root   122870 2012-12-17 16:33 config-3.6.11-1.fc16.x86_64-rw-r--r--. 1 root root   122897 2012-10-31 23:53 config-3.6.5-2.fc16.x86_64drwxr-xr-x. 2 root root     4096 2013-02-02 13:44 extlinuxdrwxr-xr-x. 2 root root     4096 2011-12-03 11:22 grubdrwxr-xr-x. 3 root root     4096 2013-01-21 03:37 grub2-rw-r--r--. 1 root root 17757091 2012-08-31 05:50 initramfs-3.4.9-1.fc16.x86_64.img-rw-------. 1 root root 18065462 2013-01-21 03:37 initramfs-3.6.11-1.fc16.x86_64.img-rw-------. 1 root root 18052180 2012-11-07 17:15 initramfs-3.6.5-2.fc16.x86_64.img-rw-r--r--. 1 root root   593313 2012-01-16 17:29 initrd-plymouth.img-rw-------. 1 root root  2444127 2012-08-15 17:01 System.map-3.4.9-1.fc16.x86_64-rw-------. 1 root root  2497974 2012-12-17 16:33 System.map-3.6.11-1.fc16.x86_64-rw-------. 1 root root  2496741 2012-10-31 23:53 System.map-3.6.5-2.fc16.x86_64-rwxr-xr-x. 1 root root  4728480 2012-08-15 17:01 vmlinuz-3.4.9-1.fc16.x86_64-rwxr-xr-x. 1 root root  4824784 2012-12-17 16:33 vmlinuz-3.6.11-1.fc16.x86_64-rwxr-xr-x. 1 root root  4822224 2012-10-31 23:53 vmlinuz-3.6.5-2.fc16.x86_64I'm not very good at sysadmin tasks, so I apologise if I am being stupid. However, I really cannot figure out what is going wrong - I would be incredibly grateful if anyone can help?
