this is not actually a problem but a question on a solution I have found that. I just want to understand what is happening in the back ground. Problem is that my computer didn’t boot. Service person told to come after a day. But he later said that his hard disk is gone. Since I didn’t had money for new in right that place, came back home. Just tried once installing Ubuntu. Set some extension as file system. I think ext3. And then inserted windows OS CD. The hard disk got detected, got formatted and now windows is running perfectly. Not found issue till now. My question: What has happened to my hard disk? How did it start working? Any thoughts?
.Ubuntu restored my hard disk solved no hard disk error
Normally, when you have boot problems, the usual cause is one of the files associated with the loading of the operating system like for example the “ntldr” file in Microsoft Windows XP and other Microsoft Windows versions. When this file is either missing or corrupted, the operating system will definitely not boot and will display the problem on the screen.
The partition is still accessible if you connect the hard drive to another computer that has a perfectly working operating system. If there is a problem with the partition where the operating system is installed, your computer will also not be able to boot and the partition is not accessible. In this case, the solution is to delete the partition, create a new partition, and then install the operating system.
Since you said you installed Linux Ubuntu and then installed Microsoft Windows after that, I think the problem is only with the operating system probably got some corrupted files. If you have a problem with the partition, you won’t be able to install Linux Ubuntu unless you delete the partition and then create a new one. Formatting the partition removes the current operating system where the issue is located.
