Hi all,<br>
<br>
Recently I compiled and tried installing kernel (2.6.39.3), which I<br>
downloaded from <a href="http://kernel.org" target="_blank">kernel.org</a><br>
All the activity that I did was to copy the .config file of my distro<br>
(Ubuntu 10.10), then the following commands :<br>
<br>
- make menuconfig ( I exited, keeping the default configuration )<br></blockquote><div> </div><div>You can execute 'make localmodconfig' after this, to ensure that you have all the necessary<br>components enabled in the .config file. It also strips off all the unnecessary ones, which will speed up<br>
your compilation.<br><br>Did you forget to run 'make' after this stage? <br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
- make modules<br>
- make install_modules<br></blockquote><div> </div><div>I run 'make modules_install' here...<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
- make install<br>
- update grub<br>
<br>
All of the above commands got executed without any errors, and the new<br>
kernel version was also shown in the grub menu. But it showed some<br>
errors and didn't login.<br>
<br>
When I tried logging to my Ubuntu distro, a blue login box(which is<br>
normally violet in color) appeared. After giving password, it came<br>
back again to the same screen without going inside.<br>
<br>
Only thing I was able to do was to dropping in root mode (from<br>
Ubuntu's recovery mode u\in the grub menu) and looking at all of my<br>
data through terminal without a GUI.<br>
<br></blockquote><div>Do you see a prompt like this ?:<br>grub><br> <br>If yes, you can try to boot your kernel by manually specifying the <br>path to your kernel image, initrd etc.<br>Eg:<br>grub> kernel /path/to/vmlinuz root=/dev/sda1<br>
grub> root (hd0,0)<br>grub> initrd /path/to/initramfs_image<br>grub> boot<br><br>Note that you'll have to replace /dev/sda1 with path to your root partition. And similarly <br>replace hd0,0 with the value appropriate in your computer's configuration.<br>
[ hd0,0 refers to Hard-disk 0, partition 0, that is, the first partition on your first hard disk. ]<br><br>Once you are able to boot into your OS fully, check your grub entries to see if anything seems <br>to be wrong and fix them. The relevant file would be /boot/grub/menu.lst if you are using the<br>
old version of Grub (and not Grub2).<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Can anyone tell how can I recover my compiled kernel and distro's kernel?<br><br></blockquote><div><br>Regards,<br>Srivatsa S. Bhat <br></div></div>
