Installing Windows 2000 or XP
-Attach the harddrive to the host computer and install a minimal bootable DOS system i.e. by booting a Win98 Emergency Boot Disk and performing the command "SYS X:" (where X = the laptop's harddrive).
-Copy FDISK.EXE to the laptop harddrive
-Return the harddrive to the laptop and boot to DOS. (If you have Win98 installed by default, you can skip the first two steps and simply reboot in Windows to DOS.)
-Run FDISK and set up your new Windows system partition on this laptop. (If you do not do this on the laptop, after reboot you will receive the infamous "NTLDR IS MISSING" error. This error may still occur if the partition is greater than 7.8gb in size)
-Then return the drive to the host and format the drive as FAT32. (DO NOT format as NTFS.)
-Repeat the "SYS X:" step to make the new partition bootable.
-Copy Himem.sys and Config.sys, too. Otherwise SMARTDRIVE.EXE won't run
-Get SMARTDRV.EXE from the internet and copy it to your Thinkpads harddrive.
-Also, from the Win2K or WinXP CD, copy the I386 folder to the harddrive.
-Return the laptop's harddrive to the Thinkpad one final time and boot to DOS.
-Run SMARTDRV.EXE first, then change directories to I386 and run WINNT.EXE, this will allow the installation to begin.
-During installation, choose NOT to format the destination partition, since it contains the installation files. If you want that filesystem to be NTFS you can convert it after installation from within Windows.

Habe ich selbst schon mal so gemacht. Wenn der Rechner kein USB-Boot unterstützt, ist das fast die einzige Möglichkeit.
