Data disaster caused by installing ubuntu7.04 on a laptop

I successfully installed Ubuntu7.04 from the hard disk iso. it was rare that the installation was successful for the first time. I was very excited after the startup. I went in for a long time. If it's enough, you suddenly have doubts! Will it damage my partition table like installing 5.10 before? After restarting, I found that XP cannot be entered as I wish. Ubuntu is normal. At first, I felt strange about this situation. Enter the following command according to the classic solution: grub & gt; rootnoverify (hd0, 0) grub & gt; chainloader + 1g

Ubuntu 7.04 was successfully installed from the hard drive iso. it was rare that the installation was successful for the first time. After the startup, I was very excited and went in for a long time.
If it's enough, you suddenly have doubts! Will it damage my partition table like installing 5.10 before?
After restarting, I found that XP cannot be entered as I wish. Ubuntu is normal.
At first, I felt strange about this situation. Enter the following command according to the classic solution:
Grub> rootnoverify (hd0, 0)
Grub> chainloader + 1
Grub> boot
The screen is black and then returns to the Grub menu!
Now, I have to go to work tomorrow. How can this be done. Because of the trust in classic tools such as pq, fdisk, and diskgen under dos, the first task is to find a way to start to dos! However, there is no CD on hand that can be started to dos. There was a store selling D-edition computer disks nearby and it was found that it had closed down. Very depressing!
The critical moment is another whimsy: I just need to burn a boot disk under ubuntu! There is a partition with a classic xp boot disk iso with menu and disk tools!
Once again, I was so depressed that it was really hard to find nero, alcohol, or other good and easy-to-use logging software in the linux World. Google has been experimenting with gnomebaker, k3b, graveman and other well-known tools for more than an hour. To be honest, these software are a little weak. It was very easy to crash without an instant. After the disk was put into the menu, even an error message suddenly disappeared. Gnomebaker, especially recommended by other ubuntu enthusiasts, is particularly intolerable.
At first glance, this method won't work, and it's just a new one: dos has so many disk recovery software n years ago. Isn't it similar in linux?
Testdisk has been downloaded, but there are too many manual functions. There is no suggestion or wizard. Many parameters need to be manually entered, so I cannot figure it out and cannot touch it.
Fdisk is also said to be quite strong. After a test, I changed a bit and clicked its default value. Save and restart!
Great! Now, not only does xp fail, but linux cannot start. Grub cannot be started. Realize the seriousness of the problem.
The next day, I went to the company and borrowed a lot of disks. n years of tossing and tossing, n more errors, and a mess was fixed.
At the beginning, the D disk can still be accessed through ntfsdos, but now it cannot be accessed, which means it cannot be read.
Three attempts to re-install zone C with the ghost disk produced by Sun Shan Hongye were half-way wrong. No matter how I adjust the partition table.
Use pq to format the drive C into fat32! The conversion is successful, but xp cannot be installed.
It is estimated that the ghost method is not reliable. I borrowed two pure xp disks and wanted to install them from scratch.
The result is that fdc. sys is interrupted somewhere.
Later, I tried n disk tools in the dark-colored toolbox. Suddenly, the D disk came out again. Dir can see the long-overdue directory!
Install again!
Failed.
In the most dangerous time, ask someone in the company to borrow the ghost recovery disk dvd from the t43 master, start the boot, and choose to confirm the restoration. After 10 minutes, enter the friendly xp desktop, drivers and so on. Check the disk. Oh, the D disk file is still there, and the data is saved. Excited.
After this incident, I was a little enlightened.
1. this is not easy to use windows + linux dual-system, because of the complexity of partitions (I guess this failure is largely due to the hidden partitions used for system recovery, a block of about 4 GB, located in the primary partition, the format is unknown, and the current time is invisible, as if it is related to the settings in the bios, some software diagnosed as the FAT format. If this item is lost, it will never go back to the factory settings !).
Either play a single system linux desktop, or honestly xp. Mixed use is extremely prone to partition table errors. If it is a machine with its own configuration, the hard disk is very clean. If it is a high-performance server, it is a low-performance server. If it is to save data, it is a big deal to pull the hard disk down to another machine from the disk, and the data is clear at a glance, if you love to copy data to it, you can solve the problem.
2. The partition tools provided by pq and linux installation programs cannot be mixed! Even partition software under dos, it is best not to mix!
3. linux desktop systems cannot be greedy! It is wise to select the LTS (long time supported) system! For example, ubuntu6.06 is running very well on my server! I just don't understand that the version number is too low and I am greedy for new things. There are a lot of new system bugs. I had to solve the problem of automatically disabling qq on gaim for a long time. Stable version is easy to use!
4. There is no need for a system (although this was my hobby) to learn practical things honestly ).
5. For linux, try to use only the classic software under the terminal. Stay away from countless bugs. And so on.
After this round, it hurt a lot. Let's sum up so much.
