Dear Lenovo users, hello.

Provide you with a way to install win7 system (**):

Lenovo official USB flash drive installation system tutorial link.

I hope it helps you and I wish you a happy life.

Generally, the system is pre-installed with ubuntu, because it is free, window7You can install it with a CD, or you can find a nearby computer company to help you install it.

1Unless you can reinstall the system yourself, you can only ask someone to install it.

Dear Lenovo users, hello.

If you need to install the Windows system, after preparing the system CD, you can boot the installation directly through the CD by booting up and pressing F12, if you can't boot, check the options in the BIOS:

1.Restart the machine, press F1, enter the BIOS interface;

2.Select restart and set the OS optimized defaults option to disabled;

3.Press F9 and then press Enter to confirm to set the default value of the BIOS;

4.Press F10 to save the current settings, i.e. restore the default values of the BIOS, exit;

5.Quickly boot the installation system directly by pressing F12 on power.

It's complicated, it's very troublesome to partition, and you need Ubuntu basic knowledge.

Find a CD, XP Win7 Win8, see what system you need, and then F12 CD start, step by step. Delete the original partition before installing and rebuild the partition.

If you install ubuntu on the hard disk, you must not install grub updates, if you install it, your hard disk is grub boot windows7, ubuntu, if you delete ubuntu at this time, you must rewrite the boot type of MBR to Windows.

When you delete Ubuntu, delete the boot partition where the grub configuration file is located, causing grub to fail to boot, you should use the dos tool disk to boot the system after partitioning, and then use fdisk mbr to repair the boot, and then reinstall the windows system, leave the remaining space, and then install ubuntu should be fine.

Dude, you're too messy, aren't you?

Here's a quick way to cut through the mess: after using PE or Ubuntu Live version to get in, find your partition, and directly use the mobile hard drive to test it back, and then you can re-tinker with the entire hard drive......

The 32-bit version of Win7 does not support UEFI boot startup, if you want to install it, you need to make the following adjustments.

1. The boot option is changed from UEFI to Legacy BIOS, so that UEFI can be switched to analog BIOS mode, so that Win7 32 can be booted.

2. Set the security boot option to disable, and turn off the security boot. Because Win7 32 does not have a corresponding digital signature.

After the setting is completed, the reboot is no longer UEFI mode, and you can install win7 32.

PS: Win8 also supports BIOS boot, so it can be directly expanded to Win7 32 and Win8 dual systems in the future.
