how to install windows 7 on windows 8

how to install windows 7 on windows 8
Because I got a few questions by email and noticed that there are many who are experiencing this problem, I decided to make a little tutorial about it. Those who want to go directly to the instructions or are not interested in technical details can skip the next 2-3 paragraphs, but it never hurts to understand something. icon smile Instalare Windows 7/8 pe laptop cu bios UEFI
Laptops sold or compatible with Windows 8 coming with firmware (BIOS) UEFI, which stands for Unified Extensible Firmware Interface is a standard adopted by a few years (it's long, but in recent years came and consumer) to replace the old versions BIOS. It is a software written in a chip on the motherboard that allows communication between motherboard and operating system, a modular BIOS that allows, among other things, booting from hard drives larger than 2TB GPT (MBR's successor ).
On the other hand, there was a new option introduced in UEFI, called Secure Boot. This option increases the security of your computer by preventing unauthorized software (malware) or unsigned drivers running on your PC during bootup.
For Windows 8, UEFI boots PC-ul/laptopul, check the stored key, check the Microsoft bootloader is signed (if it has a digital signature supported database) and finally, if everything seems ok, turn on Windows August. Of course, it is extremely fast, can not see these steps on the screen.
I mentioned above the GPT. It's the new partition table format that replaced the old MBR. Among several advantages, GPT allows to create up to 128 partitions to MBR which could not create more than 4 primary partitions. Also GPT partition assigns each a unique id, so it is not possible to write to the MBR partitions on top of the end or the beginning of another.
A GPT disk in a UEFI will be the first EFI System Partition ESP partition containing the boot files of Windows, OEM optional second partition (recovery partition created by the manufacturer), a partition called MSR - Microsoft reserved partition (later used by the operating system) and then user-created partitions: C, D, E, etc..
In the first method, which will probably be the most used by most of you because it is the easiest steps are only required in addition to the normal method of installation. It will disable some settings in BIOS and then install Windows 7 or 8 in the normal way: USB or DVD without other settings.
In these methods, I will assume that you have a license Microsoft Windows 7 or 8 already acquired. If not, you can purchase one here or here . Do not talk and do not comment on pirated license, I will not approve comments on this ultimately is what makes everyone's job at home.
Warning: lost all data on the hard drive. If you use your laptop before and have data you backup your external environment: DVD, USB, external hard, cloud, etc..
METHOD 1 - Install Windows boot UEFI with Secure Off
This method relates to the installation of the laptops that come from the factory with the options enabled at the factory explained below. Most of you will probably choose the classical method to install the operating system.
To create the USB stick to this method, you can use very easily (Next, next ... :-) utility from Microsoft,Windows 7/8 USB / DVD download tool that will require kit ISO image of Windows 7 or 8 and then reformat the stick in NTFS format, so carefully, all data is lost. You can also use this utility to create a DVD.

To start the installation, you must enter the BIOS of your laptop laptop using the corresponding keys can be: Delete, F1, F2 or F10. In the BIOS, you must first look for the option to disable Secure Boot.Typically, this option is in the Security section. A set to Disabled.

Then, depending on the laptop's manufacturer and where introduced options in its BIOS, look for the "UEFI boot mode" or "Boot mode", where you have to disable UEFI boot by choosing MSC or Legacy boot. On some BIOS option will appear SATA mode: AHCI or IDE (Compatible). Verify that the setting is made on AHCI for enhanced performance of laptop HDD.

If you attempt to boot from a USB stick on a laptop with Secure Boot enabled, you will not succeed, will not see the stick to boot. Secure boot must be disabled and then stick will appear in the bios to boot devices. Also, if you find the Fast Boot option enabled (was reported in laptops Samsung) and does not see the USB stick to boot have to deactivate.
If you use the DVD, insert it into the drive, then set the BIOS to boot from the DVD and restart, then follow the steps in the Windows installation 7 or 8. If you use a USB stick, turn off the laptop, insert the stick, enter the BIOS and set the USB stick first position in boot device priority.
Then follow the installation instructions for Windows. When you get to the partition and select the partition C, you must delete all partitions and rebuilt again with the setup utility, or you'll get the error in the image below: Windows can not be installed to Disk.
If the HDD is partitioned in MBR format will not give this error and allow Windows installation 7 or 8.
Windows 7 cannot install Instalare Windows 7/8 pe laptop cu bios UEFI
The blame is GPT I mentioned at the beginning, Windows 7 can not install on GPT. Use with confidence on all partitions Delete button until you stay just one of Unallocated space. Then, create two partitions and you want one, but two is enough for a normal user: C and D are partitions on all the New button.On a 500GB HDD for the operating system partition, ie C is enough 100 GB, and the second partition with the data (games, movies, music, documents) that Mr. remaining space left.
Then again select the first partition you created for Windows, the 100GB and click Next to complete the installation. Then everything goes normally, no other settings. Remain installed drivers, applications, etc. For drivers laptop if you can not handle or do not have, I did two tutorials for Acerand HP currently.
METHOD 2 - Install Windows UEFI with Secure Boot enabled
By this method, you can install Windows 8 on a HDD with GPT and Secure Boot enabled, so using the above advantages of these technologies. Windows 7 can not install over Secure Boot enabled.
Unlike the first method which does not need to change DVDs or USB sticks kits to install Windows in this way you will need to change a USB stick to make it compatible with UEFI boot.
Caution: In this method you can only use Windows 8 64-bit. Can not install Windows 32-bit over average UEFI Secure Boot enabled.
Download from here , Rufus program to create a bootable USB stick. This utility can be used, among other things, create bootable USB sticks on Windows, Linux Installation, write the BIOS from DOS, etc..
To create a bootable stick with Windows 8 UEFI, you need a DVD ISO image made after the original license. If you do not know how to create an ISO image, you can use this program .
Once downloaded, run the program, choose the Device USB stick point -> GPT partition for UEFI computer -> FAT32 -> Default -> check the last 3 houses and cottages penultimate law, your ISO file created earlier -> Start.

After copying is complete, you can use the operating system installation on a laptop or PC with options enabled by the first method.
In the same way you can create a stick with Windows 7 to boot on UEFI BIOS, but with Secure Boot OFF if your laptop supports to enable UEFI without secure boot automatically activate the option.
