If your need for a portable office suite is about accessing your documents from multiple computers, consider cloud-based alternatives that make “portability” irrelevant:
: Visit OneDrive.com or Office.com and log in with a free Microsoft account.
Most portable versions found online are created by third-party developers using virtualization tools (like VMware ThinApp or Cameyo). Because these versions are not distributed by Microsoft, they fall into a legal and security gray area. Security Risks microsoftoffice2019portable
: Users can switch between different workstations while maintaining their customized environment on a USB drive.

Even if the specific portable pack you download isn’t actively malicious, The websites that host these downloads are not vetted by Microsoft, and the files themselves have not been digitally signed or verified by any trusted authority. You are blindly trusting an anonymous internet stranger who decided to package up a pirated copy of Office and share it with the world. Would you give that same person physical access to your computer? Probably not.
Ensure your USB drive is USB 3.0 or higher for faster load times. Because these versions are not distributed by Microsoft,
Microsoft Office 2019 Portable is a modified version of the Microsoft Office 2019 productivity suite designed to run without installation.

A sample config.sys is included in the Grub4dos download, this can be used to replace config.sys on your boot device - if using the sample file you will be prompted to press the [space] bar to start Grub4dos.
Autoexec.bat can also be used to launch Grub4dos - simply edit the file and add entry grub.exe.
To install grub4dos code to a hard disks MBR via DOS, copy C:\Grub4dos\BOOTLACE.COM to the root of a DOS bootable drive/disk. Now reboot your PC and boot into DOS. If using Windows 9x BOOTLACE.COM can be executed from a dos box (start > run > type command [enter]).
To install Grub4dos code to the MBR of the first hard disk (usually the first hard disk set to boot within the BIOS settings) use command -
To install Grub4dos code to the MBR of the second hard disk use command -
To avoid installing Grub4dos to the wrong disk use a third party tool such as MBRWizD.exe (available here) to check the disk order. Copy MBRWizD.exe to the root of the DOS bootable device and type MBRWizD.exe /List - you should be able to identify the correct disk from the attributes outputted by the command (to install to disk 0 - use command BOOTLACE.COM 0x80; to install to disk 1 - use command BOOTLACE.COM 0x81; etc.). You will also need to copy grldr and menu.lst to the root of a (supported) local drive/disk.
Using the Grubinst package, it is possible to install Grub4dos code to the partition boot sector. Although this feature is documented in bootlace.com, attempting to install to the bootsector (using the command bootlace.com --install-partition=0 0x80) results in the following -
Use instead the DOS version of grubinst tool - at the time of writing this guide the most recent version available is version is grubinst-1.1-bin-dos-2008-01-01 (file name grbins16.exe). Use command syntax grbins16.exe -p=n [device] or grbins16.exe --install-partition=n [device] (where n = partition number, starting from 0 for first partition. e.g. grbins16.exe -p=0 (hd0). If using Windows 9x, run grbins16.exe from a dos box (start > run > type command [enter]).
grldr must be copied to the partition on which the bootsector was installed, and the partition must be active. See here for Grubinst download.
