I’ve remembered that several weeks ago my laptop couldn’t boot the OS while I was using Ubuntu 10.04 for about 1 year. I was trying to boot with my Ubuntu 10.04′s bootable CD. But it always gave me the same result, I saw blank screen with blinking cursor .
I have a thought that the problem could be one of the:
- memory card,
- harddisk, or even worse
- the motherboard (I was hoping not the motherboard X_X).
First, I checked the harddisk by removed it from my laptop, then restart again with the same bootable CD. Yupi, It was working (ye…ye..ye..ye..ye..:-D). I was glad, because at least i knew that the motherboard is still working .
So, the problem was on the harddisk. I thought that maybe the harddisk had some bad sector in it. So, without thinking too much, I’ve decided to backup all of the data to my PC’s harddisk, then performed low level format from my PC.
After finished, I had an idea to gave that harddisk new OS. So, I was choosing Ubuntu 11.04 (Natty Narwhal) instead of Ubuntu 10.04 (Lucid Lynx).
It’s all working now . But, I have to install again all of my development tools from the beginning. One of them is PostgreSQL 9.
