Reset each independent case to its stated baseline. S2, S4, and S5 are independent changes to S1; S3 has a connected-source and an isolated-source state; S6 reconstructs the target startup path after S3 isolation. The six scenarios are conditions, rather than repeated hardware trials.<\/p>\n<h3>S1 \u2014 Complete Clone Boot Path<\/h3>\n<p>Define all four target partitions, usable target ESP files, and firmware and BCD references that resolve to the target. Also, keep the source unavailable. The disk clone boot test model marks this path as eligible for an independent-startup check.<\/p>\n<h3>S2 \u2014 Windows-Only Copy<\/h3>\n<p>Omit the ESP, MSR, and recovery partitions while preserving the copied Windows partition&#8217;s reference location. Therefore, with the source unavailable, the target lacks the ESP startup files required by this UEFI configuration. Thus, the ESP omission is the immediate startup blocker; the other omissions have separate roles.<\/p>\n<h3>S3 \u2014 Hidden Source ESP Dependency<\/h3>\n<p>Keep the target&#8217;s four partition entries, but define its ESP as lacking usable Windows startup files. Instead, firmware selects the source ESP, whose BCD resolves to target Windows. For this disk clone boot test, compare the same target before and after source isolation. Assume no alternative usable startup path.<\/p>\n<h3>S4 \u2014 Clone Boot Test With the Wrong Firmware Mode<\/h3>\n<p>Keep S1&#8217;s target layout and files but select legacy-only startup on a machine that offers that mode. Therefore, the standard Windows UEFI\/GPT path cannot run through that selection.<\/p>\n<h3>S5 \u2014 Clone Boot Test With a Stale Windows Reference<\/h3>\n<p>Keep the target ESP reachable, but define its BCD Windows-device reference as resolving to an unavailable old partition identity. Assume no other valid loader entry. As a result, the chain stops before the intended Windows installation.<\/p>\n<h3>S6 \u2014 Rebuild the Target Boot Path<\/h3>\n<p>Starting from isolated S3, establish target ESP startup files and BCD references to target Windows, then define a firmware selection that reaches that ESP. Re-evaluate the dependency path. However, an eligible model state still requires an actual isolated startup to meet the pass criterion.<\/p>\n<p>For a physical validation, use a backed-up migration target or disposable test drive. First, confirm source and destination by device identity and capacity before any copying or repair. Preserve the original drive until the target passes the independent-startup check.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0gchtpw elementor-widget elementor-widget-heading\" data-id=\"0gchtpw\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Disk Clone Boot Test Results: Before and After Isolation<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-kxxbu86 elementor-widget elementor-widget-text-editor\" data-id=\"kxxbu86\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>For this disk clone boot test, compare the <strong>selected ESP owner<\/strong> with the unchanged Windows partition.
