Seems a bit confusing. If it is indeed Win95 then you should be posting in
the win9x groups. On the other hand because of the NTLDR message it appears
the pc at one time may have dual-booted with Windows NT (or later) Either
case if you're sure the operating system is Windows 95 then boot with a
startup disk and issue the command
sys C:
This will rewrite the dos/ win9x boot sector to the system drive so NTLDR
will no longer be required.

Chances are pretty good that the pc is too old and to upgrade. From the XP
CD-Rom \i386 directory you can run
winnt32 /checkupgradeonly
to see what it reports. If you proceed then save yourself some time and
trouble, given that you'll more than likely end up with an unstable OS with
all the remnants/ corruption left behind from the upgrade. Best to blow it
all away and go for the clean install.

To do a clean install, either boot the Windows XP CD-Rom When you get to the
point, delete the existing NTFS and or other partitions found. After you
delete the partition(s) abort the install, then again restart the pc booting
the CD-Rom to avoid unexpected drive letter assignments with your new
install.

During Windows XP setup, at some point, will want to confirm the previous
operating system for the upgrade; at that point you'll simply insert the
qualified product install CD for it to verify. Then the install will
proceed.

Check the pc, mb or hardware manufacturer's web site for the latest bios and
or Windows XP drivers for your devices.
