Dell notebook Inspiron 5442win10 system is not smooth

Let's change the system. No, add a hardware configuration.

1. If you have removable storage media (such as optical discs, portable hard disks, USB flash drives, etc.), unplug them and restart them.

2. If this is still the case, go to the motherboard settings, check the following items in turn, and operate:

1 Check to see if the motherboard has detected the drive correctly. If not, turn on the unit after power off and reseat the hard drive.

2 Confirm that the motherboard has detected the hard disk, and then see if the hard disk is the first boot device. If not, set the hard drive as the first boot device.

3 Save UEFI (BIOS) settings and reboot;

3. After confirming that all of the above aspects are correct, if you still can't enter the system, use the system USB flash drive or CD to reinstall the system.

The operating system could not be found... Let's just reinstall the system.

At present, UEFI GPT only supports 64-bit system startup installation! Win7 x64 installed under UEFI GPT cannot be activated with the commonly used soft activation, and can only be activated by flashing BIOS or genuine activation code! GPT partitions are theoretically not recommended for hard disks larger than 2T!

Therefore, to modify Win7 on a machine with a pre-installed win8 system, you need to partition the hard disk first, and the partition type is MBR. Then go to the BIOS, select the Security menu, select Secure Boot, and turn off Secure Boot as Disabled after entering. (Otherwise, you can't boot on the U disk), then select the startup menu, change the UEFI Legacy Boot to BOTH or Legacy First (which means that you don't use UEFI mode to change to traditional CMOS mode, legacy means traditional), and then use the U disk with UEFI boot to PE, use DiskGenius to delete all partitions, and then change the master boot record to MBR under the hard disk menu, Then install win7 in the normal way.

The book is messy. It is possible to reinstall the digital server system with a USB flash drive or hard disk, and the installation speed is very fast. But the key is to have a compatible (compatible with IDE, ACHI, RAID mode installation) and can automatically and permanently activate the verified system disk, so that the system can be reinstalled smoothly.

3. **version tutorial: How to give you the detailed **version installation tutorial in this regard? Can't be attached. will be judged by the system as a violation.

Then go to the computer shop and get it repaired. Or return to the factory, can it be turned on? If you can afford it, you can change it for a win7 system for dozens of dollars.
