This article shows how to install Windows 10 (32 or 64 bits) from Windows XP, you don't have to burn images to DVD disk or copy Windows 10 files to a flash drive. You'll need only:
List of the software:
What we will do (we have the drive C:\ with installed Windows XP (FAT32), the drive D:\ is CD-ROM drive):
The installation process:
Let's start. Open Windows XP Disk Management: right-click the "Start" button, and Left-click "My Computer", then click "Manage". Select "Disk Management" (or click "Start" button, then click "Run", type there "compmgmt.msc", and then click OK).
We need change the letter of CD-ROM from D:\ to any other value. Right-click the CD-ROM, then select "Change drive letter and paths...".
Now drive letter E:\ assigned to the CD-ROM drive:
We need to resize the existing partition C:\ to create a new partition. Because the file system of the drive C:\ is FAT32, it is impossible to use the DISKPART utility in Windows XP, it works only with NTFS partitions. Fortunately, there is freeware like MiniTool Partition Wizard Free Edition, or GParted programs.
Let's install MiniTool Partition Wizard and run it. You'll see the main screen of the program. Select the disk C:\, and click on the "Move/Resize" button:
Now resize the disk C:\ and click "OK". Windows 10 requires at least 20 GB (including a space for updates) of free space to install, so set the "Unallocated Space After" to 20000 MB or more.
Click "OK", and you'll see a new logical disk. To make it active, you must click on the "Apply" button.
You will be asked to restart the computer, and at the boot you'll see Partition Wizard running:
This resizing process may take quite a long time, so be patient. At the end, Partition Wizard will automatically restart the computer.
Open Disk Management, as it was described earlier, you'll see there unallocated space, right-click on it:
Now create a new primary partition, specify its size in MB, and assign the drive letter D:\ to the partition:
Format the partition in NTFS file system, also you can change the volume label:
After format is completed, there will be a new disk in the system. If you can't see it in the Explorer, reboot the computer.
The next step - copy Windows 10 ISO file (Windows10_InsiderPreview_x32_EN-US_xxxxx.iso or Windows10_InsiderPreview_x64_EN-US_xxxxx.iso) into the root directory of the drive D:\, then rename the ISO file into "iso.iso". Create the directory "WIN" in the root directory, and unpack "iso.iso" there. To unpack the ISO file you can use 7-Zip archiver or ISO Opener (they are freeware). This is how the root directory of the drive D:\ looks:
D:\>dir Volume in drive D is Windows 10 Volume Serial Number is A26C-9123 Directory of D:\ 01.06.2015 15:39 3 782 055 936 iso.iso 01.06.2015 03:54 <DIR> WIN 2 File(s) 3 903 197 184 bytes 1 Dir(s) 23 685 287 936 bytes free D:\WIN>dir Volume in drive D is Windows 10 Volume Serial Number is A26C-9123 Directory of D:\WIN 01.06.2015 20:53 <DIR> . 01.06.2015 20:53 <DIR> .. 25.04.2015 08:13 128 autorun.inf 01.06.2015 20:47 <DIR> boot 25.04.2015 08:13 393 718 bootmgr 25.04.2015 08:13 1 131 496 bootmgr.efi 01.06.2015 20:47 <DIR> efi 25.04.2015 08:13 79 568 setup.exe 01.06.2015 20:47 <DIR> sources 01.06.2015 20:53 <DIR> support 4 File(s) 1 604 910 bytes 6 Dir(s) 23 685 287 936 bytes free
Now let's explain the GRUB4DOS boot loader. You need the file "grldr" (MD5:fcec9e82177c23864a91d896aef261df), copy it into the root directory of the drive C:\. You can get this file here: grub4dos-0.4.4.zip. You have to modify the file "boot.ini" located in the root of the drive C:\ (remove attributes "Read Only" and "Hidden" before edit!), add this string:
Also increase timeout, add this value to that file:
The file "boot.ini" has this content:
[boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP" /NOEXECUTE=OPTIN /FASTDETECT /PAE c:\grldr="Loader"
Also you'll need the file "menu.lst" with this content:
timeout 60 color green/blue white/black foreground 000580 title Microsoft Windows XP root (hd0,0) #savedefault makeactive chainloader +1 title Windows 10 iso map (hd0,1)/iso.iso (hd32) map --hook chainloader (hd32) boot
In this file parameters (hd0,0) and (hd0,1) mean C:\ and D:\ drives, respectively.
Create this file, and save it into the root directory of the C:\ drive. http://zpostbox.ru/yt
Let's see how the root directory of Windows XP looks:
There are files "grldr", "menu.lst" and the modified file "boot.ini".
OK, let's reboot the computer. Select the Loader at startup:
Press any key to boot the Windows 10:
Windows setup will go through several screens, and when you get this screen, you have to click on the "Repair your computer":
Click on the "Troubleshoot":
Then click on the "Advanced options":
And click on the "Command prompt":
You'll see a window with the command-line interpreter:
Microsoft Windows [Version 10.0.10074] (c) 2015 Microsoft Corporation. All rights reserved. X:\Sources>
You have to navigate to the "D:\WIN\sources" directory and start the file "setup.exe":
Microsoft Windows [Version 10.0.10074] (c) 2015 Microsoft Corporation. All rights reserved. X:\Sources> X:\Sources>D: D:\>cd WIN D:\WIN> D:\WIN>cd sources D:\WIN\sources>setup.exe D:\WIN\sources>
That's all, the Windows 10 installation will begin. You'll pass through several screens, select "Install Windows only" on the this screen:
Then select the Partition 2 that were created earlier:
