Hello,
I am trying to learn real-time programming in Java RTS. I was wondering if it was possible to install Solaris 10 in my Windows 7 laptop, such that I can dual boot both of these operating systems. If it is possble, could you recommend setup instructions?
Thank you.

A few practical points that build on 's pointer and focus on what matters when trying to run Solaris 10 alongside Windows 7 (and on why a VM is usually the faster, safer route).

For learning Java RTS, run Solaris 10 in a virtual machine (VirtualBox or VMware). A VM gives snapshots, easy backups, and you can revert changes instantly — perfect for experimenting with real-time JVM settings and the toolchain. Note: a VM is excellent for learning APIs and development workflows, but it will not reproduce every aspect of native real-time latency.

If you still want native dual-boot, checklist and cautions:

  • Image the disk first (full disk image) so you can restore if something goes wrong.
  • Use Windows 7 Disk Management to shrink the Windows partition. Defragment, disable hibernation and the pagefile, and run chkdsk before shrinking to get the most free space.
  • Leave the freed space unallocated; do not create a filesystem there.
  • Boot the Solaris installer from your install media and install into the unallocated space. Be aware installers may modify the MBR or bootloader.
  • To avoid breaking Windows, consider installing the Solaris bootloader to the Solaris partition rather than to the MBR. If Windows stops booting, repair the Windows bootloader from Windows recovery media using standard commands:
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Troubleshooting notes: older BIOS/MBR disks have a four-primary-partition limit; if you already have four partitions you may need to convert one to an extended partition or use a second drive. On newer machines with UEFI/Secure Boot (uncommon for stock Windows 7 installs), Solaris 10 may not boot without legacy/compatibility mode. Finally, for true hardware-timing work with Java RTS, prefer native install on a spare drive or dedicated machine rather than a primary laptop drive.
