The option to disable touch screen in “Pen and Touch” (Windows 7) is gone in Windows 10. One needs to disable the drivers in Device Manager, as shown below:
Problem: Grub fails to boot Windows 7 in a Windows-Linux dual boot computer
Solution: This may be due to a damaged MBR.
Step 1) Boot from an installation Windows 7 DVD –> “Repair your computer” –> “Command prompt”, and type
bootrec /fixmbr bootrec /fixboot
More details can be found here
Step 2) Reboot and check if the computer can boot Windows 7
Step 3) Follow instructions in this link and install Grub.
Method 1: Using the built-in backup program
Windows 7 has built-in program for backing up. To create a system image and save to another hard drive (such as an external hard drive), go to “Control Plane” –> “Create a system image”, and follow the wizard. After that, it may prompt and ask if you want to create a recovery disc. Say “yes” and follow the wizard to create a system repair disc. Some graphical guide of this process can be found online, such as here.
To restore from a system image on another hard drive, boot into the system repair CD and select “select a system image backup”. Attach to external hard drive having the system image, refresh the list, select the image and start restoring. If everything works, you just need to wait. Another graphical guide is here.
However, it doesn’t always work (just check how people complain about the irregularities of this program). The key is once you create such a system image on another hard drive, just don’t touch it. It turns out if you want to use the image, there are several requirements on this image folder (this post also finds something similar):
Otherwise, things just don’t work. This is annoying obviously.
Method 2: using Clonezilla
Clonezilla is a free and open-source Linux Live CD for disk imaging and cloning. Its ncurse-based interface makes it a little nostalgic, but this doesn’t mean it is not powerful.
I do a full hard drive raw cloning with Clonezilla, meaning the resulted image has the same size as my source hard drive. So do check if the destination has enough capacity before getting started! Although the Method 1 above may yields smaller size, the full hard drive imaging makes it somewhat platform independent (don’t have to rely on Windows software to do the recovery), which is nice.
Conclusion: if the destination hard drive has capacity constraint, go with Method 1. Otherwise, go with Method 2.
This post illustrates it well. In a nutshell, remove Linux partitions, boot with a Windows rescue disk/USB, prompt a command line and type
This link says it all.
How to boot Mac from USB?
Answer: Hold “Option” key while booting the computer. There will be an option for Windows.
How to install multiboot system?
There are scenarios where you need both Microsoft Windows and Linux(es) in one computer. There are some installation guidelines:
Always install Microsoft Windows first. If not, it will rudely erase the boot information of other operating systems previously installed.
Install a “clever” system that can handle multi-boot grub well after MS Windows. Ubuntu can be a good option. Install it disk-widely. For example, if you only have one disk ‘/dev/sda’, then install the grub in ‘/dev/sda’.
If you need to install more Linux(es), install each grub in its own partition. For example, if ArchLinux’s ‘/boot’ is in ‘/dev/sda7’, then install the grub in ‘/dev/sda7’.
When the grub information changes in any system, use Ubuntu (the second system here) to update the grub disk-widely (‘/dev/sda’). The commands are simple:
How to rescue a broken grub (grub2)?
One can install/update grub from a LiveCD with Grub2
Boot with a LiveCD
Assume the root is in /dev/sda7 partition
That will interpret grub2 configuration file and write to ‘/boot/grub/grub.cfg’. And then,
to finish grub installation.
System time is not corrected after daylight time savings in Linux
This happened when I have a Windows-Linux dual boot computer. Installing and updating NTP did not help. The solution was to sync the BIOS clock by booting to Windows, and the boot to Linux. The system time in Linux was updated correctly after that.
