VMware ESXi 5.x: Archived Installer Steps and Driver-Media Limitations

This is an archived installer walkthrough for ESXi 5.x, with a 5.1 boot example. Match the actual supported server, controller, firmware, installation media and license terms. The source mixes captures from different releases, so the pictures are UI examples rather than one verified installation sequence.

1. Boot and review the installer license

Boot the intended optical/ISO media using the matching host boot mode. The source selects the ESXi installer and presses Enter while the installation environment loads:

Review the actual media’s license and use F11 to accept/continue when appropriate. This source capture explicitly says Beta License Agreement; it does not establish the terms of another release:

2. Verify the installation target and keyboard

Select the intended installation disk. The source capture is a 40.00 GiB VMware virtual disk; it does not prove recognition of a physical RAID controller. If required storage is absent, first verify compatibility and the correct driver/media process; do not select a different disk just because it appears in the list:

Choose the correct keyboard layout and continue. The source illustrates US Default, which must match the keys actually used to enter the administrator credential:

3. Set the root credential and confirm the intended install

Enter and confirm the actual root-account credential; only masked fields are present in the source. The original says at least seven characters, a historical policy illustration rather than a universal sufficient-strength rule. Follow the actual release’s credential policy and protect the issued credential privately.

At Confirm Install, verify the target and the warning that it will be repartitioned before F11. This particular capture says ESXi 6.0.0, even though the article is labeled 5.x:

4. Complete the installer and reboot from the installed disk

Wait for the actual completion result, remove the installation media and use Enter to reboot as directed. The source’s completion capture identifies ESXi 5.1.0 and mentions a historical 60-day evaluation; it does not establish current licensing or eligibility:

The source’s post-boot local console is another 5.1 build example. Its tiny CPU/address text could not be verified reliably during localization, so those host-specific fields are explicitly replaced with placeholders in this English illustration. It is not a newly captured host or a network test result. The source-page tooltip is translated and is not an ESXi menu action:

After a real reboot, verify the intended build, installed storage driver, local-disk boot and actual management connectivity. Installer completion alone is not a full host-health or compatibility certification. None of these actions was performed by this translation.

Appendix: the source’s old ESXi-Customizer 2.7.2 workflow

The appendix links OEM downloads labeled for Windows 7 and Windows 10, then uses the old ESXi-Customizer GUI. The tool author’s own English page says it supports ESXi 4.1/5.0/5.1/5.5, does not work on Windows 10, and has been unsupported since August 21, 2015. The OEM link label is not independent verification of a Windows 10-compatible modification.

For its supported historical 5.x context, the source describes these inputs/actions:

1. Obtain the verified original ESXi ISO and matching controller driver/package from an approved source.
2. Unpack the tool and run ESXi-Customizer.cmd.
3. Select the ISO, the matching VIB/package and a local NTFS working/output directory.
4. The source unchecks automatic update checking, then selects Run. The tool author’s old guidance instead encouraged checking for updates when possible; this checkbox is not a required storage-driver operation.
5. Inspect the generated ISO and log and verify its provenance/content before use. A selected input or a Run button is not a successful build result.

The GUI capture has blank ISO/package inputs and an unchecked update box. No generated ISO is shown. ESXi-Customizer-PS is a separate successor using PowerCLI ImageBuilder; it is not the same application, and no new command line or compatibility promise is invented here.
